Uhm I don't know if it works, but I saw something on one of SDooms video's
just get a blank subaction or something and then use that one to create an extra move, but I guess you also have to get the animations for it to work

but in psa, start with a blank subaction, I guess that should work...
and if it doesn't, well, then that's not a real surprise to me because, I'm not a psa'er so yeah
