How to create seeks for higher rated opponents

You can't. Everyone's coach tells their students to only play higher rated but the math doesn't work.

if i just do a “quick start” 30 min game seek- there are default parameters which seek a little lower but i have found that when i get an opponent +200 the game is almost always aborted so there’s that
i remember when you only had to do this one time (adjust seek settings) and i just had to select the “30-min” game and settings were in place
