[HELP!] Flip sprite instance

hello there, i'm making a menu for my game, it has a big BG image, so i splited it in several tiles to save vram, it has some repeted inverted tiles, so instead of waste vram using repeted tiles, i want to reuse only one instance, and make clones and invert them, but my problem is, when i want to give the flip effect, it applies to all instance, i didn't find a way to apply a flip effect to only one instance, so i need help finding a way to make this

Use negative Width and Height values. Negative Width will flip your tile horizontally and negative Height will flip it vertically.

oh, that was so simply!, i felt so dumb XD

thanks you very much!
