Using Datagen with ParchmentMC mappings

[CrypticVerse]

Description

I am trying to use model datagen with parchment mappings, and I am confused. I know how to make block and item models, but do not know how to make models for slabs, stairs, etc. For yarn mappings, I type this in:

BlockStateModelGenerator.BlockTexturePool maplePool = blockStateModelGenerator.registerCubeAllModelTexturePool(MyBlocks.TEST_BLOCK)

And reference it with this:

maplePool.slab(MyBlocks.TEST_SLAB)

Another issue I run into is trying to register signs, which in yarn you use like this:

maplePool.family(MyBlocks.TEST_FAMILY)

In ParchmentMC, trying to register a sign throws this error:

Caused by: java.lang.IllegalStateException: Family not defined, at class ModelGen.java:28

Does anyone know how to register slabs, stairs, signs blockstates in ParchmentMC mappings?

Is this even possible?
