Is there a way to make Waygates only work for ground units??

I figure you could make some similar functionality with various functionality, but I'm thinking if it's possible to just modify the Waygate ability to not work with Air Units then that's probably the way to go.

just a quick idea:
make the ability work only for ground units? i fear the waygate ability is hardcoded and won't accept such settings.

I've tried this before but couldn't get it work, it's a stubborn hardcoded thing.
