that's it, but can i write a query against that? we'd want to join this to core.groups and core.membership.

in case there isnt, I just figured out that I can point labkey to it's own pg tables as an external schema, which lets us directly query against the underlying postgres tables. this could be kinda useful whenever labkey stores information we need, but doesnt expose it...

querying the time of last study reload would be another example of storing the information, but not exposing it.
