Has anyone with 2+ characters had any luck having follow, assist etc working in BGs?

I am using Mosg2's setup, and it does not work for BGs yet, and i am curious if anyone has had any luck making a follow setup work in BGs.

one idea, would be to setup a 8 or 16 or however large the BGs are assist / follow keys, so you can just find your main in the list, and hit the button to make that toon the main?

im at work, so i cant test this right now, but we should figure this out, my marauders are itching to kill people!
