Option to exclude some applications from combining and forcing others to combine

I would like to be able to exclude some applications from ever combining their window icons even when the taskbar is crowded.  I would also like to be able to force other applications to always combine their windows even with plenty of space on the taskbar.  I'd like to do this while still allowing the rest of the applications to combine/decombine based on taskbar width.

Basically, on an app by app basis, I'd like to be able to click on the app in the 7TT settings and select from "never combine, always combine, auto"
