I realize this isn't the sort of thing you'd want to allow generally, but is there a backdoor way to add items to a readonly collection that is generated from M:N relationships? I'm trying to mock my persistence layer, and need it to look the way it would after loading w/ a prefetch. Any suggestions? Thanks -Jeff
