Adobe Illustrator VDP (Variable Data Printing) PDF multi-page support

Hello Everyone,

I’m working on a VDP (Variable Data Printing) project in Adobe Illustrator, but I’ve hit a roadblock and need your help.

I created a CSV file with 13 rows, as shown in the example below. This method works perfectly because each PDF file is separate:

Example (this setup works):
/Users/graphic-1/Desktop/HW/H1.pdf
/Users/graphic-1/Desktop/HW/H2.pdf
/Users/graphic-1/Desktop/HW/H3.pdf
/Users/graphic-1/Desktop/HW/H4.pdf

However, what I want to achieve is slightly different:
Instead of saving each page as a separate PDF file, I want to use a single multi-page PDF containing all 13 pages. For this purpose, I updated the file paths in my CSV as follows, appending the page number after the file name:

Example (this setup did not work):
/Users/graphic-1/Desktop/HW/HMulti.pdf:Page 1
/Users/graphic-1/Desktop/HW/HMulti.pdf:Page 2
/Users/graphic-1/Desktop/HW/HMulti.pdf:Page 3
/Users/graphic-1/Desktop/HW/HMulti.pdf:Page 4

Does Adobe Illustrator’s VDP feature support multi-page PDFs, or am I making a mistake somewhere?

I’d appreciate any insights or solutions!

Thank you!
