Is it possible to add flex spots for runes that revert back to what you had before after a game?

Is it possible for Riot to implement flex spots to runes (meaning in a preset rune page you've made), that would enable those runes to be altered flexibly to adapt to enemy champion choices or team comps...and then have those runes reset back to what you had saved before right after the game you played ends.

Is it possible for this option to be implemented (flex runes that is)?
