Filter on linked Doctypes

Is it possible to filter on properties of a linked Doctype in the Report Builder? E.g. I’d like to list all contacts linked to the customers of a specific Customer Group.

Or is there an other way to achieve this?

It will not be possible in Report Builder type Report, try using Query Report.

Is this feature available to hosted users? I can’t seem to find it.

anyone?
