Auto-select Mastery and Rune pages?

Let me start of by stating that I am very forgetful when it comes to changing my mastery and rune pages based on which role I am playing in each game. There have been many times where I have entered a game playing as the "Jungler" with my ADC rune and mastery pages selected.

I think it would be great if while creating new rune and mastery pages you could set champions for the game to auto-select these pages for you. Example: If I select Twitch or Tristana on the champion selection screen my rune and mastery pages would automatically switch from whatever they previously were to my ADC rune and mastery pages; and if in the following game I select Master Yi, they would change automatically from my ADC pages to my Jungler pages. It would be excellent if summoner spells could be auto-selected in this manner as well.

With this update teams would never have a problem with their ADC accidentally using sub par pages and summoner spells for their respective role on the team.

Just throwing the idea out there in hopes that my fellow summoners will agree and Riot can make this update possible in a future patch. Please vote or comment below and let me know what you think! Thanks for your time.
