[1.11.2]IBakedModel question

[Astelot]

So I was browsing some forums, and I stumbled upon TheGreyGhosts minecraftByExample and I thought I could try out block with custom model loading (Github - MinecraftByExample MBE05).

 

Now I'm wondering,  as I have 3 unlisted enum properties with each having over 20 variations, instead of pointing ModelResourceLocation directly for each single model as it is done in the example above, is it possible to use some kind of different format, for example using blockstate for each property?

 

I found IModelCustomData but I'm not sure if that is the right thing nor how to use it correctly.
