Kinda hard to explain for me but I would like to assign a slot for "any" block. kind of like

profile MyProfile activate HOT1
     HOT1
          "minecraft:block"

I'll do some research about this.
But minecraft:block even if it exists as an ID will exclude any modded block.
Might not be soon but I'll probably do something about this.

not really possible to be done in non brute force way
