There should be a RSI option in RHP. Meaning, that if someone wants to play 50 games with players between 1200-1400 rating and a 7TO/7TB they can simply by entering the information and that RHP selects the last 50 players within such a rating to make a move and send an invite. The person for example would have 25 games with white and 25 games with black and a 7/7 time control.
It would then be up to the person receiving the invite to accept or decline the invite. As for the games in white, the person makes their move and waits for an accept or decline.
This would make it easier than having to go through profiles and inviting players one at a time.
