Would Like to have "These relationships have a specific ordering" on "mash-up" rec-rec relationship, like we do have on "compilation"

An example where this is useful: https://beta.musicbrainz.org/recording/f3b418ae-ace1-46e1-9504-3430eaa8d891
This has loads of mashups but they are a) mixed into eachother and b) other sixx mixx's have a mashup of a mix of already mashups and stand alone tracks that are "mashed up in the mix" for the first time"
additionally many other such mega mashups and mega mixes will also have "order" of things mashed up
