How do I change a tile in my tileset to an sprite?

I am working on a random Dungeon generator and i have on my Tileset different "symbols" to identify the items i will replace. have no idea how to do this.

Tilemaps and sprites both come from image files. You can edit the tilemap image and crop out the tile you want as a sprite, either in construct 3 or an external image editing program.

Or, you could create an instance of the tilemap that is sized one tile worth of width and height, and set the tile to the tile you want. This isn't the intended use of the tilemap object and not recommended though.

Have found a other solution :)
