"Fill" Option Team Builder Addendum

The new team-builder is great. Its functional, tries its best to get everyone what they want, and lets everyone look at and edit picks as necessary before locking in completely. It circumvents a lot of issues (if used properly), such as lack of tanks, disengage, engage, what have you.

The one thing I feel should be added is an expansion to the fill option. I personally cannot top lane efficiently, but I am average in the rest of the lanes (and thus these would be my preference), and best at Jungle. For a match, I would select Jungle as primary. For the secondary however, since I am average in rest, I would choose fill - and in the odd chance I do get top lane, I cry inside. I rather not select a specific secondary as I know I am average, and I do not want to take away any chances from the team winning if someone else can carry from said position.

Would it be possible, then, for the fill option to have a deselect value? I.e. If I choose fill, I can deselect top lane - leaving me with support/adc/mid - which I would be completely fine with.

This might be unnecessary globally, but this is my opinion. Let me know what you think!
