You know how when you go into the Nurturing grounds there is a thing for choosing maturities and which pets to Nurture?
Anyway I was think you could add a bit where you can chose what breed of pet you Nurture, for example
Luffox or a kelpari

It has been suggested before, and turned down by Krin, for the purposes of 1) maintaining the challenge of nurture boards during fests, and 2) trying to make sure no breed gets neglected from nurturing due to the species being less popular (via people ignoring them because they're specifically nurturing more popular species for the essence drop chance)
