Addition to Fill option, all roles except X

This has probably been said before but...

I liked the old system of pick priority before only for the fact that i played different roles consistently. The new 2 role system is an improvement but the fill option is basically just another support button I think in all my games as fill I got jungle once or twice. I don't mind supporting but with the option to eliminate that as a choice of role to change things up I think would be an improvement. I would go so far as to even not allow this choice UNLESS you filled or played support recently similar to how it promises one of your two choices after filling or playing support now. I like playing different roles so fill would be perfect if it wasn't just play support 99% of the time.
