How do I get my Primary Role in Dynamic Bullshit?

So I've been playing ADC for a long time. I main that role. I never get my role though. I choose ADC > Mid, I still get mid. ADC > top, I get top, ADC > jungle, I get jungle, and if I were to pick ADC > support, I'd clearly get support. So every time I've been stuck with a feeding shit bot lane. Just my 2 cents on dynamic shit.
