Say I want to read some spooky reads for October.
I'd like to create a Challenge that has a bunch of books on it, but you complete the challenge by

• reading any x books, or
• reading any y pages, or
• reading any z hours.

In other words, it's a combo of how people set Book Goals for the year, but for a Challenge.

Currently you can create a Challenge which meets the first criteria (read 5 books) but you can't create one for read 1000 pages of that set of books.

Eg,
I create my 2026 Spooky Reads challenge.
I add 10 ghost stories and horror books to it that I'm interested in.
I set the Challenge Page Goal to 1000.
Once I read 1000 pages in that Challenge (whether 3 books, or 5 books, or ...), then I've completed the Challenge.
