Hi @suep89793525, the script you linked by CrazyPanda is great, and I probably could have adjusted it to run the way you want, but it wasn't structured ideally for that, and anyway I always like to learn, so I have written my own version. Please give it a try. Hasn't been tested much, so please let me know here if you find a bug and I will fix. It should work with placed .ai, .pdf, and .indd files.

* - Do not specify `layerNames` in settings if you want
* to choose from *every* layer in every placed item.
