There is and there isn't at the same time. There is
this script, but it hasn't been released yet. You can try and keep tabs on it once in awhile, but it hasn't had an update for awhile either.
Or if you don't care if it isn't an ATB, there is Gubid's TBS (or GTBS) and you might be able to get someone to code the neutral side to be Player 2. Other than that, there isn't one to my knowledge.
