Captains in Teambuilder Should Have More Options

When teambuilder first came out, I was really excited to be able to try out different team comps without having to assemble 4 friends with similar skill levels at the same time. However I was really disapointed when I found out you basically have no options as captain. You can run double jungle or 5 mid, but you can't make any choices about what champions/types of champions you want on your team. I orignally thought team builder would give me a chance to run team comps such as all aoe ults comps, all global, full poke, split push, 4 supports and a hyper carry, all infinite scaling, super early aggresssion, etc. However, as captain you just get random champions in each lane and if you decline them the wait gets progressively longer and nothing stops you from getting the same champ you don't want 3 times in a row. I think captains in teambuilder should have an option to search for specific champions (i.e. you can pick several from a list so in an aoe team I could look for amumu, sejuani, maokai, wukong, evelyn, nunu, or rammus in the jungle role). I know this would increase wait times a lot for some people, but I think it would be worth the wait sometimes.
