here's what i think you could do:
use powershell to check out a folder, and then script out any objects.
then use powershell again to add any new items, and check in the who folder, with a comment like "changes found + date; then it would ignore items that did not change automatically.
i googled "powershell check in TFS" and this was the first worthy link:

once that is working, it should be easy to create a scheduled tas that runs once a day or so.
