For a column icon rule/saved search, is there any way to differentiate between an integer column value that has been deliberately set as "undefined" from one that has not been set at all?
I want to show an icon/make a search for books missing a value in #chaptercount, but a lot of books don't really have traditional chapters.
I thought about just putting '0' in for those books, but that would appear in the book details and break the math if I want to divide pagecount by chaptercount or something.
