I really think that can not be done in C2.
1 - Take a tilemap tile
2 - Use the tile as a sprite
I think that is not possible.
You could do it but the individual tile should remain another tilemap object, the tilemap object has some restrictions, for example you can not rotate its angle.
You would need the Canvas plugin but ... I do not recommend using these plugins that do not have conversion to C3, this is because if in the future you change to C3, the use of these plugins will be an inconvenience.
