Touch Stay Guide Link guest url

When Touch Stay sends the digital guidebook url to the "New" hostaway booking it does it 1 minute later (which is great) but it opens the reservation and puts in the url into the Touch Stay Guide Link field and when it saves it it sets the reservation to "Modified" 

This then triggers another email and notification that the reservation status has changed form New to Modified.  So for EVERY SINGLE RESERVATION I now get two emails and two notifications.  This is a background function and therefore the entry of the Touch Stay Guide Link url should NOT trigger a modification.
