As a fill in Dynamic Q

I understand Most people dislike Dynamic Q, and with good arguments and points, But if you keep Dynamic Q around i would like to ask for a small change. There are many times when I went into Q and found others who use fill as well, for they play most roles, and end up getting the one they don't know well or just didn't want to play. I would like to ask that When you enter as fill the Secondary an optional input that allows you to select a role you do not want. This, I believe, will Help player and their team's experience by moving players who don't want or simply don't know a role, out of that position.

But this is just one players thought and it may be good or bad, but it's my opinion among many and i am interested in others thoughts on this matter.

Thank you for taking your time to look at this post.
