Is your feature request related to a problem? Please describe.
Every time I go into a pet battle in which I have no upgrades for that battle, I have a popup telling me that. But sometimes upgrading the rarity isn't the goal, but a side goal of leveling up your battle pets.

Describe the solution you'd like
A toggle that puts you into a levelling mode, where you don't get that popup, and even helps track leveling progress, or reminds you if you left your team at all 25s after a battle.

Describe alternatives you've considered
A toggle that just stops that popup from coming up every time there isn't an upgrade to rarity in the battle.
