Straight to the point; I think being able to exclude lions from Feed All Play all would be a great improvement for several players.

As someone who feed stat items to my groupie as well as use FAPA constantly there's a few times where I've forgot and feed all my lions before I could give him anything. I'd love to be able to starve a specific lion while I keep the rest of my pride happy and fed, as do others I'm sure of it!

It could be on a lion's page directly, where you can lock and unlock the FAPA feature for this specific lion. To prevent forgetting and actually starving your lion to death, there could even be some kind of warning on the RO's message telling you that x lion using the exclusion feature is having high hunger and that you might want to consider putting him back on FAPA.

*I'll work more on this topic later, I promise!
