Macro Suggestion

If there's a way to do this I apologize. I haven't seen anything showing how to do it though.

I'd like to be able to put multiple key functions into a macro. For example: If I press 1 it'll cast Cure. If I press Shift+1 it'll cast Cure II. If I press CTRL +1 it'll cast Cure III.

I know it's kind of possible to do this by reassigning key binds. But I'd love to be able to clean up my UI a bit.

So assign them they keybinds on your hotbars.
Then disable showing that hotbar.
