Story or Story arc tag suggestion

I was wondering if you could add a tag to for books or doujins with stories that continue over 2 or more chapters. One shots are fine but I love the stories that last longer. I just wish it was easier to find them.

Examples:
Female Hero's Journey
Koume Keito Box
Metamorphosis
Welcome to Tokoharu Apartments
It's a Straight Line Once You Fall in Love
Hanafuda
Excursion Day 99
