Name group - possible?

[Lexje]

Hi folks,

A quick search did not give any reply, so I ask here:
Is it possible to name groups in Xtreme 5 Pro?

Also, I'd like to understand the meaning of the little circles in front of the sub items figuring in the Name gallery. Sometimes they're half filled with red sometimes completely filled with red.

Thanks for your help and patience!
