Special slot for cta

Hi, is it possible to add special slot for only cta?
(where it is impossible to put a weapon, not to upset the balance)
and assign it to a special button, and not to work the general swap

we have extended inventory and merc gear for comfort play ,but only 2 slot for swap,
where is the first for weapons., and the second for a weapon or cta

in pve its to be comfort have 2 slot swap for weapon and 1 for cta
because there are imunas etc, and cta more comfort than add bo barbarian in game

in pvp no need use cube in inventory and change every time
