How do I make a custom treasure map to one or multiple of my own added structures?

[yaboytommy123]

I'm making a mod that contains a map to 4 structures. How do I create a locator map to these structures? I'd prefer if the one map went to all the structures, but I can make separate ones if that is not possible. It would be exactly like a Buried Treasure Map, but to different structures. I'm modding with MCreator, so if there is a way to do it through their presets, I can use it, but I also know a bit of Java so I could use custom code to create it. Please help!

That's why I said I know a bit of code. MCreator codes with Forge, so I can add a custom element using my own code.
