I've an idea to improve a revit functionality, which I think should be the basic of the program we use daily with all my colleagues of Dura Vermeer.
The idea is:
To add the possibility to select all groups
Activate all the detail groups 
And this should activate the detail groups in all sheats 
Example:
I use within projects sometimes more than 20 groups within different sheats.
Right now I need to activate the detail groups for each sheat.
Kind regards,
Marwan
