Just anchor a white text frame at the beginning of the page (text frame) first footnote …
you will find … by script!
(^/) The Jedi
But not perfectly.
If I add a new footnote before the first comment,
If you add something, the script will need to update (remove) all the anchored frames and add new ones!
… But you just need "1 click" at each update! So, it's simple to play.
You did not send me a script.
I understand from you that I need to set an anchor for the first row
In the footnotes. And it worked well. But if I add a new comment before the first,
I wanted an automated solution that works perfectly.
As Adobe knows how to do.
I've written such a script for a client in 2016!
I've just indicated you how it works and how, imho, it would have to work in your case.
You can contact me in private unless you want to wait for a guy who will do it for free for you!
Can you please send me the script?
