Hello, I have a kind of urgent question. I assumed that the different price box meant I could sell several episodes of my comic (one project) separately. For example:

Only episode 1: $6

Only episode 2: $6

If you want both, $12

But it seems that I can only make it like this:

Only episode 1: $6

Episode 1 and 2: $12

Which is rather inconvenient. Is there a way to do what I want to do in the same project page, or the only way is to set up different project pages? Thank you.
