Combine Selection Sets

[monday1313]

Scenario:

Merging multiple instances of a project that has multiple selection sets.

Say I have a Rigged model of a character that I want to create a crowd of. I merge 300 copies of the Model's rigging scene into a concert scene.

Now I have 300 sets named like: "Left arm set" , "Right arm set" , etc.etc.

Say I want to merge all the Left arm sets into one set called "Left arm set all".

I'd like to be able to select them in the set editor window, hit a button and create a new group. Then have the options of deleting all the old groups or keeping them for some unforeseen need.

For now I would have to select each individual group and add them to the new group that way, that's not always as quick as it would seem.

Thanks!
