I think the reason why they do not allow us to add macros to hotbars/crosshotbars from text commands is because they do not have fixed names (like any other text command equippable item).

They could use standards like "macro_01", "macro_02", etc... to solve this issue, but maybe it takes too many resources in their evaluation.

....otherwise they would have added it already for sure.

btw ty Bixby for the copy suggestion... hadn't thought about that =)

as a crafter would be very useful to exchange on the fly macros on the hotbar as well as actions in order to perform different rotations for different recipe difficuly
