OMB 8.0 (with broadcasting and multi pc support, unlike the wob variant) now has support for key re mapping feature:

So for instance if you bind Alt-T to Mama's train feature and Alt-L to mama lead.

If you remap L:T then on main you can hit Alt-L and get a train and set lead to the main, without having to have the lead following the last one (which would happen if you just plain broadcast the Alt-T)
