Suggestion for the devteam for a mechanic

Hello I hope this is the right board because my idea is not directly a gameplay mechanic I think. So my idea is that you may introduce the fill position but with one exception for example you choose fill and for me it would be toplane so you don't get filled into the lane of your choosing. I think I might not be the only person enjoying a feature like that.

Looking forward to an answer
