"Feed All" button for fields?

The title says it all, but there's multiple ways that you could go about this. 1.) Outright adding the "Feed All" button after clicking a berry to feed PKMN (This would be done for each berry) 2.) Adding a "Feed-All Upgrade" that can be purchased either, -From the field menu, so that the "Feed All" button is limited that single field (the upgrade can be bought once per field for any amount of fields). -From the Labs, which would allow the above to happen OR give all fields a "Feed All" button. Of course, with something that could potentially break PFQ a far as Interation Points and PokeRus goes, there'll have to be some cons to balance the pros. Maybe the button will only give half the Interation Points, or half the XP gain w/ Exp Share. (By the way- I don't know if this was suggested before and declined. I literally just hopped on to post this thread after getting the idea.)

I can't get the links at the moment, but this has been rejected multiple times. EDIT: Here is a summary of rejected suggestions. The feed all suggestion is in there.

Aaaah, okay... Thanks for letting me know.
