I know it's not the same but maybe this works?
Edit:Code:/micon "Full Thrust" /ac "Full Thrust" /hotbar set "Chaos Thrust" DRG3 DRG3 /ac "Chaos Thrust" /hotbar set "Full Thrust" DRG3 DRG3
O wait this won't work .. you can't switch Macros with hotbar set.. you would have to use hotbar copy for that :/
