My suggestion is instead of having a check mark in the dynamic difficulty search results, is to have the # of levels instead. I find that for the single level difficulty songs, if it is my first time playing it and I do not max everything, it will level me down on in general. I know I can adjust manually in riff repeater, but it can be difficult to decide which was the optimal one I was at before. Plus having the # of difficulty levels may encourage people to add more.
