Ability to mark favorite champions before match

So I got to thinking. I almost always play the same 10 or 15 characters over and over again. Why isn't there some way to mark your favorite champions or champions you want to play beforehand so they show up first on champ select? I don't usually play super frequently, and I sometimes forget about a champ until suddenly I realize I've been wanting to play said champ but have gone with others just because I forgot. I know that sounds a little silly, but think about it. If you have just a few champs to play per lane and you get auto picked support, it's nice not only to see the support champions you have but also know which ones you usually play. I am a Computer Engineering major, and have a lot of experience in coding, and I don't imagine it would be difficult to implement something like this. If it is too difficult that's cool, but if it isn't that's even cooler. Thanks for listening! [poppy-wink]
