Grouped objects - Adding/Removing objects to a group

That´s what I was afraid of. 

If I ungroup the items then I lose all of the motion paths associated with that group. If I use Ctrl+G (as discussed above) I can add an object to the group, but then to get the whole group to move as one, I have to recreate the motion paths I already created.

Here´s an example of what I have/need to do. Let´s say I have two squares that create Group 1. I have motion paths (Let´s call them motion paths 1,2, and 3) and triggers that work with Group 1. I used control G to add a square to Group 1, thus creating Group 2. When I try to change the triggers to work with Group 2, motion paths 1,2, and 3 aren´t options, so to get the same effect I´d have to re-create the motion paths. It took me hours to get the motion paths just right so I´d like to avoid re-doing it and it seems like there would be a way to do so.

Does that make sense? I´m basically wanting to do the same thing discussed above regarding SL1 and was hoping it had been addressed in SL2.
