Chamption select roles suggestion

I guess this has already come up at some time. I would just suggest to have this implemented.

I'd suggest to have the the option to choose the role with "least preference" or in other words, not wanting to play. I like to play 4 different roles (I am just bad at the fifth) and would like to fill in any of these 4 roles. This would also give more options and a bigger variety than just 2 roles. my 2 additional roles may be 2 others do not want to play. I do understand the issue with 90% choosing "not support" but autofill can still be on. It just doesn't need to be used that often anymore when people choose more than 2 roles.

I am playing high plat low dia elo and my fifth role just is not in this level while the others are and I'd like to play all 4.
