It would be very handy to be able to have 'Add to Group' added to the right-click popup window when you rmb a location or object in a window in dev. Upon doing this another drop window appears with all current created groups (based on type Obj/Loc).
This would save time adding objects/Loc to groups manually.
Alternatively or as well in the property section of the object (I see there is such a thing for Locations already); there could be a built in default selection property 'Belongs to an Object Group' and sub property if ticked to select which object group. This method would also be quick if you are already in properties assigning the object to a custom property you already set up. We can already do this for an object belonging to a Location Group, which is for Static objects. But being able to easily put objects into other groups this way would save us time.
