How do I stop Construct 2 from duplicating tilesets

Hey, I use the tilemap object to make the map for my level in Construct 2. However, when I add a new layer of tilemaps and re-use the same tileset, I notice in my textures folder the same tileset has been duplicated and named after the 2nd layers name. How do I link them all to the same tileset image to prevent file size rapidly increasing as the project continues to have more levels added and tilesets re-used.

Thanks in advance!

Are you making duplicates of your tilemap object?

You want to have a single tilemap object, and drag multiple instances to the layout view.

I would do that however one layer is solid tiles and one layer is effects without any collision to go on top of the previous layer.

You can put instances of the same object on multiple layers.

Have the solid behavior on it, but in the event sheet on start of layout, you pick and set enabled or disabled for the proper instance of the tilemap object.
