Custom Plant Help Needed

I'm new to Mcreator and I'm trying to make custom crops I have two seeds one tomatoes and the other onions thing is I want the first two stages to always be the same without making 2 different crop blocks. Is there a way for the first two stages of the crops to keep data on which seed was used to plant them? ( There's three stages of plant cropstage1, cropstage2 and I'd like the final stage of the crop be different based on what seed you used.)
