Has Had [Item] in Inventory Procedure Block

Hello! I would like to suggest a new Procedure Block called something along the lines of "{Event/target entity} Has had [Item] in Inventory", which would function like a regular Item in Inventory block, except it'd activate when the Player's had an item in their inventory at all during their playthrough, instead of just the current moment. This would allow for things like "Powerups", which would give an effect given by an item that would stay with the Player even after getting rid of the item, or Advancements that trigger once the Player's had a list of different items, instead of just one. (E.x. an Advancement for obtaining all Spawn Eggs).
