Merge NBT data with Custom Block

Ok. So... This might be impossible with MCreator, but I know procedures can do a lot. Here is the step-by-step of what I would like to do:

• Check if a player right clicks on a monster spawner with this item in hand (I will call this item Item1)
• Check what the monster spawner spawns (zombie, spider, etc.)
• Save that data to Item1

This next part might have to be a seperate procedure, idk.

• Check when a player right clicks on any block with Item1
• Use the data saved to Item1 from the monster spawner to spawn that entity, kind of like a spawn egg
• Delete the data saved to Item1

Any help would be much appreciated!
