My player selector mod (proof of concept) has this fully working and I will explain the mechanics of how to do this via lua once I finish up with the modding magazine issue number 1 and release the finished stock scripts and the custom compiler needed to start compiling your own lua mods. I have been super busy as of late trying to take care of all that as well as deal with projects outside in real life that also need to be finished before winter arrives...and nearly done with those too.
