Usage of Comic series category

I'd like to add something there but I'm not sure how it's supposed to work. Is it correct if I create a different item for each issue of a comic series (for example Batman #207, Batman #208, Batman #209...) or is each item dedicated to a series as a whole (for example, Batman)? I wanted to add each issue separately, but before creating many many many items I wanted to ask if it's correct ahaha.

No currently it's for entire series only.
