yea that would be nice. it would affect pvp though. and pvp balance is very delicate as im sure you know. if someone forgets to brings regs to the fight its a game changer.
if you have the patients it is possible to make a macro to pull 100 of each reg you need -> [keyguard -> put in loot bag for safe keeping. so you would literally only need to push a hot key once an hour or so to reach the same result. this is something that could be used on the run even.
