Re-Using Custom Block.Java files?

Hi there, I am working on a mod that has these plushies that come in a variety of appearances. My initial idea was to have one PlushieBlock.java file to determine the block's properties, as apart from texture visuals, these blocks will be the exact same. However, it seems that when I make a new block in MCreator, it creates a new "___Block.java" file for that individual block. Is there some way to fix this, or is it fine to have a unique java class for every custom block?
