Well I have 4 pages of Lex saves because I was leaving a save at each major choice for exploration's sake.
I was going to start on Page 10 for Erynn, 20 for Layla, etc and leave gaps for the future; It's what I did for that one game about college that shall not be named.
Unfortunately, Intertwined doesn't show "Page 1" at the top like the others do, so you literally have to count as you click next. I suppose I could use the first slot as a page label, but it would be way easier if the function existed
