Autofill summoner spell swap

When placed in jungle for autofill, you are automatically given smite. Which I love, it makes surprise junglers not forget it. However I and others on multiple occasions who main a single role tend to forget their spell had been swapped, and end up in a game or two with smite in lane. What I propose is that the autofill smite swap be made a temporary shift, and that after the game your spell be reverted to what it had been before.
