Toggle antigrav option?

[Digital Merc]

I may be missing it, but there doesn't seem to be a way to turn off or disable the antigrav upgrade once acquired.

This can become problematic when trying to swim downward, move in a tightly confined area, or make multiple small jumps [the game thinks you just want to use the antigrav instead]

Every now and again I wish I could just press a button to turn off the antigrav upgrade for a few moments, do whatever I needed to do, then turn it back on.

It also makes end-game "mega skyscraper water diving" impossible once the antigrav upgrade is acquired

Sure, I can add a bindable key that enabled/disables the antigravity pack.
