Tryin to "identify" a unit dragged into another unit

[shaggai]

Question: In the 40K files we started to make use of the drag-and-drop mechanic. The problem that we are facing at the moment is the need of a unit to take on either a tag or stat which can be used to identify that it has been dropped into a specific unit, so then that unit can be modified.

At the moment it looks like units which have been dropped into another unit are simply there, there seems to be no child/parent relationship between the two.

Is this something that is possible of would this take a new iteration or major build of AB to accomplish?
