Option 1: Use Episode Release Year:
Format: Select all
{ d.year }
Format: Select all
{ episodelist.findAll{ it.s == s }.d.year.bounds().join('-') }
Format: Select all
{ sy.join('-') }

Similarly you can get Total Season Count like this:
Format: Select all
{ episodelist.s.max() }
Format: Select all
{ sc }
