Version.sg_uploaded_movie uploads and updating linked entities - how to modify behavior?

Our SG site has automated transcoding enabled, the default behavior. When we upload a movie file to Version.sg_uploaded_movie, the thumbnail for the linked entity, in most cases a Shot, appears to be linked to the latest Version.

Only problem is, as we get closer to the delivery for a project, the latest version that vendors sends us often ends up being a DI matte pass. This is making the thumbnail for the shot very confusing. Is there a way to turn this functionality off, or somehow limit it?

The Thumbnail field is a query field, you can alter the query and filter out versions you do not want to be considered for the Thumbnail version.

By default it’s the Latest Linked Version.

Thank you! That did the trick!
