Hey! Thanks for purchasing the package!
If I understand correctly what you're saying. You want something similat that's in this gif:
It basically takes a bigger grid of sprites, and based on the coordinate it repeats that pattern, you can look at the code here: https://github.com/Vinark117/Tutorials/blob/main/CustomScriptedTiles/VariableTil...
This example is not a rule tile, but it wouldn't take long to implement it with the rule tiles. If you can wait a few days I can add the feature, so you could use it with the editor.
If you have any other requests feel free to post it.
