Playing with ur DUO Bot lane

I think it would be really nice to be able to choose The primary and secondary lane BOT/SUPPORT when u play with your dou partner. to be able as u, ur partner aswell to take the same lanes to be sure u play together bot lane. We are playing already for more then 1 year and now its kinda awkward when the matchfinder finds a game were he has to go other lane and i play support as ussuall cause there are less players who like to play suppor.

I think for duo partner this would be really big help to let them play always together if they like
