Velocity keyboard vs preset

I am using the velocity calibration for getting the optimal velocity curves for my keyboards, and it is a really great feature. However, I have a few challenges:
1) I use different keyboards, depending on which rehearsal room I am in (varies with the different bands, I don't bring my 20+ kg keyboard with me to all rehearsals). I am trying to find an easy way to switch to the right velocity map, depending on keyboard.
2) I freeze the velocity curve, so it is the same for all presets. But some presets have an alternative velocity curve as part of the preset, which is now overridden by my keyboard adjustments. Is there any way to get both?
