is there anyway we can increment variables? For example, lets say i have a sorcerer who can cast 5 level 1 spells per day. I store the 5 in a variable called "Spell1". When I use my "Magic Missile" macro, I want to decrement the "Spell1" variable from 5 to 4. Later on, when the character rests for the day, I want to push the "Rest" macro button and restore the "Spell1" variable back to 5.
