Seasons of Drabbles

I've just added a crossover nomination for Historical RPF/Opera Singers RPF with 2 characters, and I puzzled over how to nominate Farinelli there, as he's already nominated under the Historical RPF fandom (by me in the last round, as it happens), so I'm hoping using his full name tag as it appears on AO3 by now, but still keeping him under Historical RPF, is okay? I figured it would be less confusing than having the same character tag appearing under 2 different fandoms, though he of course fits within the Opera Singers RPF fandom too. I can change this if needed, obviously.
