Autofill for Support Mains

I am a support main. 99.99% of my games are support. So I wanted to branch out. Picked top/supp for a draft. Then got told I'd be autofilled because of my role choice. How about no. Since I already play a role no one wants 99% of the time. . . We should get credit for branching out as long as we are mixing our main roles in. The last thing I want as a supp main trying to learn a new role is to be forced into something I def can't play or don't want to learn like JG. TY.
