Queueing up

Hi! I enjoy the new look of the queue and the fact that the way it's designed makes us players pay more attention while in lobby, however I wonder if it's absolutely necessary that when we're queining up we have to choose a first and second role, I would much rather have the option to for example only choose jungle and if that would result in a longer queue, that is fine with me. As it is now if I choose jungle and then fill I almost always get put as support, and seeing as I have no preference at this moment between the other lanes and I actually only want to play jungle at this moment I have to gamble and maybe choose mid or bot as my second seeing as those are popular roles but when I choose those and If I get placed there I am surely not as useful as if I was to get jungle.
