How do I Register "Damage" to Individual Tiles in a Tilemap?

I want to be able to damage tiles when they are hit but I want some tiles to be more durable than others. I know that tilemaps can have instance variables but they seem to apply to the whole tilemap and not just the tile being affected. I want the individual tile to remember that it is damaged. The only solution I can see is to create multiple tilemaps with different variables of "durability" and when it gets damaged I replace it with one of a lower durability. Is there some other solution possible or is having many different versions of a tilemap the only way of doing it? Thank you in advance for your response!

You can use an array to store each tile's state in, indexed by the tile indices.

Thank you. My question feels dumb now. Still wrapping my head around how to properly integrate arrays into what I want to do. I just tried storing the tile state in an array and subtracting its "health" when a bullet collides with it, however it only subtracts it once. So with a default value of 3, it subtracts to 2, but won't subtract further upon further bullet collisions. I don't know if I need some kinda for loop or something but I have included a snapshot.

You can't use CurValue, you need to index it explicitly: Array.At(...,...)

Thank you for your help! I have it working now with this.
