I suggest that users are able to indicate while they're at a companion LGS, that they are willing / ready / able to participate in other forms or formats of magic, i.e. being at a commander event and being willing to jam a couple games of modern or pauper during downtime or after the event concludes.
I feel that this would make playing at LGSs a more build-your-own experience, especially with formats that don't see widespread or frequent events such as pauper, dandan, pre modern, tiny leaders, etc.
I also feel that an optional indicator that signals a user's willingness to teach formats, provide decks for learners, or offer things like coaching and counseling for play in more competitive formats while they're not participating
