Pick many won't allow user to pick many
If you are serious about consistency, you need to use checkboxes. Almost every computer program written in the last 50 years uses radio buttons to indicate that only one option can be selected at one time, and checkboxes to indicate that several options can be selected at a time.
So when you create a bunch of radio buttons, SL automatically puts them in a Button set, which means that only one of them can be selected at a time. Choose checkboxes, and that doesn't happen.
I would strongly advise you not to use groups. Groups don't play nicely with anybody, and especially not with triggers and states. Ungroup the groups, choose one item to be the base item, select and copy all the others. Edit the state, and paste all the others onto the Normal state. Now you have one object, and it can have states and triggers applied to it.
I did try it with checkboxes in and out of groups and they kept going into one button set where it only allowed one to be selected. I'll try again, hopefully it'll work this time!
