Date when you watched an episode

Is it possible to add the date when you watched an episode? This would be a very nice feature.

This is not possible.

If you are connected to trakt SeriesGuide uses today’s date. You can set a specific date using the trakt website (scroll to the bottom below the episode description, tap the trakt link to get there quickly).

Could you at least display the watched date on the episode page?
Thank you.
