Invert channel pressure?

[Kabletx Profile]

Does there happen to be in method by which one can invert channel pressure? As it stands right now, when you use channel pressure with a high velocity note it immediately jump straight into modulation crazy land. If it were possible to invert the values, I 'd be able to hit a high velocity note and then smoothly swing into the channel pressure/ aftertouch. I'm not sure if I'm missing an option, or if it's just not there... Thanks for the amazing app!
