simply make or edit a macro with
/target playername
/cheapshot 1 (this line is actually longer but i cant remember off the top of my head)
now press this button like a maniac nonstop while looking for the other rogue

Wierd thing is that even if that person gets the cheapshot off on you, you'l get it off on them aswell

doesnt work with ambush because positioning is trickier.
