Resolved Scaling tiles in a tilemap but also splitting them into normal sized tiles via script

I want to make it so that in my game you can scale a tilemap to make the world bigger. The problem is, I don't want to just have it normally scale into big tiles like it normally due to how I want the players interaction with the environment to work. I want to have it so that, for example, if the player sets the world scale by 2 a single tile would become a 2x2 tile area rather than a single tile that is twice as large. How do I do that?
