Using Set List Maker last year, before the new version, I used to transfer all PDFs into Dropbox from where I'd add them as needed when adding documents into Set List maker. Since the changes when looking to add a document the only locations Se tList maker offers are iCloud drive or files on my iPad; Dropbox is not included as it used to be. Is this correct, and must everything now go through iCloud, or have I just missed the way to involve Dropbox in the process?
