As a user, i would like to be able to add a private tag(s) to squad mates from previous matches.
Why: I want to be able to set a custom tag for a competitor that would be visible only to me during the registration and squadding process to help drive my future squadding decisions. I do/do not want to squad with certain types of competitors. This could be a set of canned tags like good RO, always resets stages, does not reset stages, poor RO, delaying the match flow, unethical actions, suspected cheating, etc.
This could be a supporter only feature
