Marking Files in Dropbox to link to Workfront

Hi all -

We are using Dropbox to link files into Workfront across multiple projects. Is there any way to mark a file (with a tag, metadata, a color indicator, anything) in Dropbox (without altering the image itself) that will pass through to Workfront? It would have to be on the Dropbox side as the same image could be linked more than once. We are trying to know what is final and what is not universally.

Let me know if any of you have something figured out for this.

Thank you!
