Moving your U.A. to storage or to a vehicle inventory that is in your inventory? Of course this way you can't use U.A. at all with other items only if you move it back to your inventory.
Why would you want to? Mind Essence has a considerable markup value compared to Unlimited ammo. So it would cost you a lot more to heal with ME than with UA.
SME cost 100% at TT, UA you get 101% from converting, so basicly it is 1% cheaper to heal with UA.
Yeah, you will burn your UA faster while healing with it.
But ofc in the end it's about trying to heal as less as possible.
