Active Work Odata Collection Pre-Filtering

Hey everyone,
I'm trying to set up an Odata based collection - Active Work (certain analysts want to see all SR&IRs on the same page), but I want this to be pre-filtered to only show work items which are assigned to the specific support groups (let's name them SG1, SG2, SG3, SG4 for the sake of tihs example). Anyone help a brother out with a filter query on this?
Thanks!
G.
