Doctor Who ordering

Hey,

I am slowly adding my Doctor Who collection to Plex. Is there a way to tell Plex that a certain file should be played "before" or "after" another?

So for example, If I watched "The Name of the Doctor" then it would play "The Night of the Doctor" followed by "The Day of the Doctor", "The Time of the Doctor", and then "Deep Breath"?

This would be the final episode of series 7, a special short 'minisode', two specials and then the first episode of series 8.

Thanks,
Neil
