Honor/Mastery Banner Choice(s)

It would be nice to be able to choose your honor/mastery banner(s). At least the ones you have unlocked up to and including your level.

Purple is my favorite color I even hold multiple champs at M6 mastery just because the M7 banner is blue. Similarly I favor the Honor 4 banners for their purple color.

Considering both are purely cosmetic I don't believe this would have much of an impact on the game despite being a simple and much appreciated feature for those like me.

Also does anyone know how to hold honor 4 without being uhh... dishonorable?
