Currently I want to neatly organise a batch of 500 PDFs in one InDesign document. I placed them slide by slide into my document, and now I thought of adding a small box on the corner of each slide which indicates the names of the individual PDF files. I did this via the
Type > Text Variables > Insert Variable > Image Name
option. Adding the box and the variable to the master slide adds it on every page, but it does not "intersect" with the images/PDFs, thus it does not recognise the file names ("< No intersecting link >").
Is there another way to solve this, apart from adding the box with the variable to every page individually?
