[2020] Riot, please allow us to manually change deck covers

It would be cool to be able to change the deck covers of your decks.

Currently it bothers me having a Yasuo deck with 1 Tryndamere in it and have Tryndamere on the deck cover. That just does not feel right.

Edit: An option to be able to show multiple cards in one cover would be cool as well. And I think it should not be restricted to champions only.
