With ID it seems that we can only select several elements on the same spread or page.
Do you know any way to select all elements on a same layer and on all the pages at the same time?
And would it be possible to paste them in place in an other document?
At the same time, no, but it may be able to be automated spread by spread using a script. I'd ask over in InDesign Scripting
Thanks Peter! I will check the scripting avenue…
