Updating Automation Ideas in Automation Hub

Is there a way for someone other than the submitter/process owner to update automation ideas that are in the assessment phase? My team has a few ideas submitted with blank Detailed Assessment sections that now need to be filled out.

The person who originally submitted is no longer with the team. It doesn’t appear I can update them as they are now, I believe I am a Standard User. If I was designated as a collaborator would I be able to update? Any other roles who can? Or do we need to scrap and re-submit from scratch?
