Basically i want to do this;
macro 1 "uses a gashal greens to summon my chocobo. Then replaces itself with macro 2 on my hot bar"
Macro 2 " uses the withdrawal companion action. Then replaces itself with macro 1"

The reason: depending on what im doing, im constantly summoning and withdrawing my chocobo. Is there any way i can keep this down to 1 hotbar slot? I know you can use a macro to rearrange other hotbar actions, so is there a was to swap macros the same way?
