Signature - how to change signature on a video a team member created

A Dubb user asks this question thru email: If somebody on the team creates a video for use by other team members, is there a way to change the signature that appears on the video landing page? Currently, I cannot get the signature line to change if I want to send out somebody else’s video.

If there isn’t a way, what do you recommend as a solution?

Currently, there would be a few ways to do this.

You can go into that user’s account and change their Profile Picture/contact info etc.
This will change the signature below all of their videos though and not just the one video.

You can also download your team-mates video and then reupload that same video into your own account and that will put your own signature below the video
