Extract annotations from multiple pdfs

[aarontimo]

Is it possible to extract highlights from multiple pdfs stored within the same Zotero record? For example, a long doc/book is broken into Pt I and Pt II and I would like ZI to extract annotations from both pdfs. At the moment, it only appears to extract from the last pdf. Can this be achieved via a nunjuck template?

Thanks to Claude 3.5 Sonnet, this template will cycle through and extract the annotations from multiple attachments within the one record in Zotero. I thought I would post it in case it is useful to anyone else.
