A suggestion for champion select

Sorry, I didn't know where to put this type of post. Yesterday I did a couple of games with my husband irl, and I was the last to pick, we needed an ADC but I couldn't decide. That's when the idea game to me. A champion role filter! Sure we have the name filter but, when you know what role you want but own over 100 champions and only have 20 seconds to find one and decide, the name filter doesn't help. If we could filter champions by role during champion select, it would be easier to find certain champions in a small time frame, especially if you have trouble deciding like I do. It's just a suggestion but what do you guys think?
