Mulitple ATV units and the watched/unwatched tag

I have multiple ATV units installed in my house accessing shares on a 3TB NAS.

When I watch a downloaded video file on unit A, as expected, it shows as watched but on the others units it shows as unwatched.

Would it be possible to have Media Player write to an attribute of the video file to trigger the watched/unmatched flag instead of storing it locally? That way all my units would show the same watched/unwatched status.

I would also like to see something like this as I have 3 Apple TVs.

same for me… i’ve asked this for a long time… i have multiple ATV and sync would be great.  sync with doesnt work well at all imo
