I'd think saving a view.
And then the double SetView script will be the way to fix it.

You might consider disabling IWT on the main toon.
By this I mean use macros to enable/disable CTM (Click to Move).
While leaving IWT keybound on all toons, so anyone can be a slave with CTM/IWT.
Off: /console AutoInteract 0
On: /console AutoInteract 1
With IS Boxer, I auto disable CTM on the main and enable it on all slaves, just by PiP swapping.
But I'm not running a melee team yet.

That way, no matter how you spam it, only the slaves move.
So the masters camera doesn't change.
Not sure if its better for the master to auto run at the target too, or if you'd be better off with manual control of the master.
