Getting at a level number from another document

[eadocX Support]

Short answer is no…
..but this is a feature we used to have in the very first, hard-coded version of eaDocX, and one which we’ve been thinking about re-instating. But it won’t be easy!
Just so I understand what you need, is it to have a reference in document #1 which says e.g. ‘See Document #2, page 46’ or ‘See Document #2, section 3.4.1’?
