Tilemaps: How to turn a tile into a prefab?

So, I have a basic tilemap setup for a platformer. They have the basic colliders around them as well but how do I go about adjusting the colliders for each tile?

I don't really know what source to look at or where to go so I'm pretty stumped at this point. but I want to adjust the box colliders for each block and use different scripts for each one as well. Is there a way to turn a tile in the tilemap/palette feature into a prefab?

EDIT: I just purchased the super tilemap asset and I'm figuring it out. All good now
