custom 4th axis options

I am looking to have a few more fourth axis options into PathPilot. I am designing a tombstone, I have an existing cheap amazon er32 that I got working, a custom multispindle (er16 spindles with small nema 24 motors powered externally) setup for a repeat job, and a (probably) stock rotary table..

I don't want to have to change our my ratio and my settings every time I swap it out..

Can anyone help?  I'm pretty sure the picture is the file I need to modify.  I can add the stuff into the one in common that I have done in the past.
