Allow filtering for Me and group in dashboard widgets

[diderich]

Widgets on the dashboard (see below) allow filtering records for me, all, specific users, and specific groups.

Feature request: It would be great if there would be a possibility to select records belong to me + a specific group.
Rationale: I would like to see, for example, leads entries related to the marketing department as well as mine in a single widget, rather than having to set-up a widget for leads entries belonging to me and a second widget for leads entries belonging th the marketing group.
