This way the same key works for all slots and you can just switch character, hit the Set Target key and in a matter of seconds you have defined a new Lead for all your slaves. This works no matter what party member slot they see each other in.

EDIT:
If what I said didn't make sense (been awake for over 24 hours) I could make a short video guide tonight showing you how to do this, if anyone is interested. Right now I need some sleep though.
The one problem with Chazz's system until he provides a walkthrough for everyone, is that on occasion character 1 will target character 2 in slot 2, and character 2 will target character 1 in slot 3. So far I don't believe he has provided a walkthrough to cover this occurance. This is the only thing keeping me from swapping over to his system as I've worked around this issue with the system I setup pre variable target.
