Dynamic queue - Choosing a NOT role

Dynamic queue has a good idea; you are able to queue up for your two most preferred roles and so should be able to get something you like. Even if you're not a picky person, you can choose "fill" for one the roles, letting the algorithm know that they can match you with whatever. As someone who will gladly 'fill' from time to time, though, I feel there is a crucial aspect missing: the ability to specify NOT to play a specific role.

I realize this may have some people saying, "Anything but support," but given that the format already allows for you to say "Mid/ADC," thats not really the point of this. As I'm sure many people will agree, there are just some roles that people do not like playing/are not good at. For myself. I hate playing top lane. I don't like playing the meta champions for it, I don't like the constant split pushing aspect of it; i just don't like it.

I am sure there are other people who don't like ADC because they don't farm well early game or people who don't like jungle because they don't like having to find a balance between farming and ganking.

I am fine 'filling' for a team comp. I just would like to be able to specify I am cool with 4/5 roles. and since the dynamic queue damn near locks you into a role right away, I think this should be a feature.
