You cannot force the Dictionaries. I think you are lucky having some synonyms to play with.
Use the Description Panel (not comments) to explain, you can edit that at will.
I believe you need to cultivate a new ZA team to help you with agreements and so shift Likely when needed.
PS I have just seen Tony's comment - milder than normal!
Do note that iNat is still using an old name, despite his assertions - best not challenge him!
