Date Added facet

I realize that resources aren't technically "added" to the web app, and that there's no "Added to user library" metadata to filter with at this point, but perhaps the web app can sync the date added from our desktop?? Just thought it would be nice to be able to view those resources purchased in the last x-number of days when on the web app. Ideally, we would have metadata that reflects the date the resource was licensed to the user, but if not, can you just sync the desktop "date added" meta data so we can see recent purchases via the web app.
