Matching making options for solo que players

I think for the next season a great feature to implement for normal players would be the option to have them no be able to be matched with premade groups. When I play solo in normals there is nothing more toxic than a premade on either team trash talking or even inentionally feeding and ruining a game for you. I think the option for people planning to que up solo would be to be able to turn off matching making with premade groups.
