One Free Dodge for Promos

So I just got done with dodging champ select for what would have been my final promo game. The reason being someone got auto filled to support and heaven forbid if they actually play it like the rest of us. He said he would not play support and picked Zed as his champ. I dodged forgetting that it counts as a loss when you are in promos and lost promos overall.

I'm not saying we should be allowed to dodge any game that is a promo game but I at least would like riot to entertain the idea of one free dodge for that one special case where someone in champ select refuses to play the role they are given. I just don't think it's fair that I should just have to go in and "hope" this guy does not feed and help us try to win the game. It makes me feel like I just have to put all the work I spent in these promos on the back of someone who just can't stand auto fill, refuses to follow it, and more than likely causes the entire team to implode before the game even starts. Is one free out too much to ask for?
