Could a system be made to save W.I.P. masteries in case you can't save in time?

Sometimes my mastery page does not get saved by the time when the game loads in since i didn't get a chance to hit save. Why not implement a system that auto saves runes, masteries in progress, and summoner spells at their current position and layout when the champion select lobby ends and the loading screen shows? Then at least I could go into a game with some masteries and runes that i wanted rather than ones i can't really use.
