Related Files?

I want to add the ability for members to see related files when viewing files in Downloads. For example if a member is viewing an eagle file in downloads there will be a widget that will recommend other bird related files to the member. Ideally the recommendation will be based on tags, or file title name, or other parameters which I can set. I don't see a way to do this in IPS admin and didn't find anything like this in Marketplace. Is there an existing solution? Is this something which is easily built?
