Macro to track Sorcery Points

Hello all, I've been bashing my head against this for a couple days trying to figure it out and I've decided to just come to you all! I'm using the 5eOST sheet and ammo tracker to try and created an ability for one specific character that would allow me to choose between a spell level, and have it automatically deduct a specific number of the class resource for each corresponding thing. Do you have any ideas or pointers to help me accomplish this?

I don't really like a macro set for that cause sorcerers like to fudge their slots and points.  I actually manage all my sorcerers with spell slot cards and a sorcery point cards and I deal them out the conversion rate when they throw down a slot or some points.  I do use the dealer api to make a macro to quickly dish out the card conversion back to them after I delete the card they throw down to crunch or spend.
