Edit Internal iMates

[MistakenEngineer]

In order to edit any of the highlighted iMates the following has to happen:

1. Bring the iMate out of the composite group
2. Perform an edit on the iMate
3. Delete the composite group
4. Re-group the iMates to the composite 
5. Edit the composite definition to the original

The same can be said with adding another iMate to the group. You just can't do it. Please fix this issue so that you can easily edit internal iMates and add more to the composite group.

This idea is part of a group of ideas under iMates Overhaul that seeks to improve iMates.
