Engine Vibration for ShakeIt Motors?

I'm currently using 2 large rumble motors for "bass" shaking, rather than using audio transducers. So far this is working very well with one exception - the effects listed under "ShakeIt Motors" aren't the same as those under "ShakeIt Bass Shakers", specifically "Engine Vibration" doesn't exist. I've tried to simulate this using RPMs but that's not gotten me all the way there.

Is there a way to create an analog using a Custom Effect? But if so is there a way to assign a custom effect to separate channels, as right now I have 2 custom effects I use with my pedal rumble motor so if I created another I'd need that independent from those custom effects.

Thoughts?

Thanks!
