Team Builder Runes/Masteries/Summoners

They should have a thing where if you pick, for example, Bottom Lane + Marksman in Team Builder, it automatically gives you a preset set of runes, masteries, and summoners that you can change according to your own personal taste. So for example, it would give me my ADC runes, ADC masteries, and flash + heal. That way, the incident of "I thought I had the right masteries!" doesn't happen as often.

And maybe even do that with individual champions instead of just roles?
