I want to sell a digital magazine on Itch, and one of the annoying parts is that to sell each issue individually I need to create a new page/product for each issue. This adds a bit of work, but more importantly, it segments the audience, who needs to go digging to find the latest issue.

I think it would be a similar problem for episodic games, and things of that nature.

I'm also open to alternate solutions (maybe a forced "collection" when people search for your keyword, instead of going to a product, they always go to a collection of all the products).
