Updating app gallery (screenshots) on existing Zoom app listing

Our marketing team is hoping to update the screenshots in the app gallery on our reviewed & approved Zoom app that is listed in the App Marketplace. We are not updating the app at this time, but it looks like they can not submit these new screenshots without providing technical design documentation.

Is there a way we can submit just new images to the app gallery for our existing app listing without having to repopulate the technical design section of the app submission, since our app is not changing?
