-- Conditionally modify macros
-- Make a Plumber Macro by adding #plumber:[command] to the top of the macro body
-- Implementations:
-- 1. plumber:drawer        Create a custom SpellFlyout by adding # to your regular macro. E.g. #/use:Dalaran Hearthsone
-- 2. plumber:drive         Added to your regular mount macro. Summon G-99 Breakneck in Undermine. Change the icon.
