Adding new custom Dashboard to Company's dashboard section

I have created custom Dashboard Chart and Dashboard containing monthly sales of the company.
I can view it using Customization - Dashboard - Show Dashboard.

Now I want this to be attached/displayed Company’s dashboard top section as shown on below link, but unable to find menu/link to add it. Currently the Company’s dasboard section shows nothing other than other doctype links (SO, Invoice, etc).
