How do I keep the filename of my first document when joining multiple print to PDF?

PDF24 Creator - Version 8.8.2

We just switched to PDF24 Creator from PDFCreator by PDFforge and are generally pleased with this software.

One issue is with a common workflow to print multiple documents to a single PDF. With PDFforge, the merged document would generate the default save-as filename from the first document in queue as expected. With PDF24, clicking "join files" in the "PDF24 Assistant" window results in a new "Document 0" and this is the default filename for save as.

As a workaround, I instructed the users to 1. Print all required documents to PDF24 PDF; 2. Select the first document in queue and click Save as PDF; 3. Ctrl-C copy the filename and then click cancel on the Save As dialogue; 4. Click Join files in PDF24 Assistant and then click Save as PDF; 6. Ctrl-V paste the filename (copied from step 3) and then click Save.

Is there a way to preserve the name of the first document in queue when joining multiple prints?
