Route on PDF+ files in Esko AE

[Hans77]

Hi,

I'd like to route the creation software of any PDF in AE.
The routing allows PDF/Normalised PDF/PDFPLA, or I can do it by SmartName checking the Creation tool and/or the PDF Producer.
However, I noticed that the Creator tool is the same as the original PDF, which is not changed if the file is edited and saved in ArtPro+.

Has anyone found an alternative way of detecting if the file is created with ArtPro+?

Thanks!
