Can the content used in Sitecore PXM / APS be controlled by the workflow even when editing in InDesign?

Question

Background

I use content that is controlled by the workflow in the Sitecore Print Experience Manager (PXM *) project. One of the great features of PXM is the ability to save content changes to Sitecore when viewing an InDesign stream.

Problem

Unfortunately, when you save a content item to Sitecore, it saves data without involving the workflow in the item.

Question

Is there any way to enable a workflow with the InQuery Sitecore PXM connector?
