Sales Invoice Print Format - edit Timesheet columns

Dear ERPNext Community,

is there any possibility to change the columns for the Timesheet Table, in a Sales Invoice print format, which is not a custom Format?

It would be also possible to hide the table (as it is not shown in the customization) and just add a new timesheet table which customized columns. But how to remove the standard one without having a custom print format?

I would aprecheate some help. Thank you.

A snip shot of your issue will be helpful.

Right now I am working with this custom print format and instead of just listing the timesheets as a whole I want to only list the timesheet detail single entrys which description:

    {% if doc.timesheets -%}
    <div style="page-break-after: always"></div>
    <div class="timesheets">
        <h3>Timesheets</h3>
        <div data-fieldname="timesheets" data-fieldtype="Table">
            <table class="table table-bordered table-condensed">
                <thead>
                    <tr>
                        <th style="width: 40px" class="table-sr">{{ _("Sr") }}</th>
                        <th style="width: 150px;" class="" data-fieldname="timesheets" data-fieldtype="Table">
                            {{_("Date")}}</th>
                        <th style="width: 300px;" class="" data-fieldname="timesheets" data-fieldtype="Table">
                            {{_("Note")}}</th>
                        <th style="width: 80px;" class="text-right" data-fieldname="timesheets" data-fieldtype="Table">
                            {{_("Hours")}}</th>
                    </tr>
                </thead>
                <tbody>
                    {% for ts in doc.timesheets | sort(attribute='start_date') %}
                    {% set timesheet = frappe.get_doc("Timesheet", ts.time_sheet)%}
                            <tr style="page-break-inside: avoid;">
                                <td class="table-sr">{{ loop.index }}</td>
                                <td class="" data-fieldname="timesheets" data-fieldtype="Table">
                                    <div class="value">
                                        {{ timesheet.get_formatted('start_date') }}
                                    </div>
                                </td>
                                <td class="" data-fieldname="timesheets" data-fieldtype="Table">
                                    <div class="value">
                                        {{ timesheet.note }}
                                    </div>
                                </td>
                                <td class="text-right" data-fieldname="timesheets" data-fieldtype="Table">
                                    <div class="value">
                                        {{ "{:.2f}".format(timesheet.total_billable_hours) | replace(".", ",") }}
                                    </div>
                                </td>
                            </tr>
                    {% endfor %}
                </tbody>
            </table>
        </div>

I did not find any solution, solving this without a custom html print format.
