Checking what fluids are stored in a block

Basically, I was trying to make a block that takes liquid latex as input (have it be any fluid), I want to check if the fluid is latex, or tagged as latex for mod compat, there is no way to check what fluid is stored, I could use nbt, however, say another mod pumps latex into the machine, there will be no created nbt tags, and if I cannot check what fluid is stored to then give an output, and I want multiple recipes in the block, then this won't work
