Forum Post: Zetadocs : path to send the document to sharepoint, how to set the ID of the contact in the path?

I have SharePoint 2010 and NAV 2009 R2 AND Zetadocs to send documents to SharePoint. Everything is working fine. I would like to change the path of the destination. I have found some settings where I can add a folder as "Company", "DocType", "Date". These 3 items are available in a dropdownbox.

But I would like to add a folder with the ID of the contact. How can I do this?
