Store tile HP

[shrewd nimbus]

I'm making a game like terraria where you can create and destroy tiles.
Tiles have HP and when hitting a tile you do X amount of damage to it. To show the damage each tile has 4 damaged states sprites (in the tilemap).

Where should I store the tile max HP and current HP ?

One way would be using a scene collection.. https://youtu.be/U53wf7ybnIs?t=43
