Sounds like some sort of limitation like "can only use # times," or perhaps "only when there are no enemy pieces within # spaces," could be of help, from the perspective Aurelian proposes.
The former sounds to me like a possible use for t in XBetza; for example, t2mNN would allow two non-capturing Nightrider moves per game. I don't know how I'd code the latter, but I do know that I've come across several pieces with that type of limitation (and its inverse).
