Naming format doco's Series by year

Just wondering what format I would use to get the info to show properly for documentaries that the series is a year not a number?

Eg for one like this – 2015 x 27 - Wild World: Borneo

Normally it would just be like S15E27 format if the series was just 15 but what do you label it to get the current lookup for a year like 2015?

Thanks for your help.

You can just use the 4 digit year as the season number.

I’ve just tested it quickly here, and this works here for me.
