Is it possible to make more than 10 layers in Google maps?

Question

Google

Hello. There was a need to create a map in Google with the addresses of dealers, as well as add photos of stores. But I ran into a problem that only 10 layers can be added to Google maps. and I need about 50. Is there a way or a program how to do this?

Answer 1

And if I just need to create it in layers and in an amount of up to 30, is it possible to do this somehow?
