Persistant Block Data(after destruction)

[1Mangomaster1]

I have a boolean on my BlockEntity that determines something..
However, I want this value to be saved even after the block is broken and replacd(this way, seprating the blocks who have it as TRUE in the ItemStack, an NBT perhaps)
How can I do it so blocks with that value set to TRUE will drop this variation of the item with a different NBT, that when placed down, will make sure the newly created BlockEntity will have this boolean set that way?

Basically I want to be able to destroy and place a block with a certain state and have that block remember that state(also be seperated from the same types of blocks who are not in that state in the Inventroy, prob using NBT)

How do I work with "BlockEntityTag"s?

you can take a look at the ShulkerBoxBlock and ShulkerBoxBlockEntity as an example
