Group selection move, surface snapping on, pivot doesn´t move

Greetings!
If i try to move a group with surface snapping on, selecting the group in the viewport does not select the GROUPACTOR, and after moving the group the pivot stays on the same place. Becouse the Groupactor is not selected, its difficult for me to Visibility->show selected only. Becouse it hides my selection , becouse it hides the unselected group actor. Selecting the groupactor from the content browser is not an option for me, becouse if i got like 200 groups, its hard to find which one is the one im looking for.
Thx
Regards
