I have a Magento EE 1.9 website running two different themes for the same store: one for desktop and the other for mobile. The theme is changed based on user-agent using the design exception string under System -> Design -> Theme.
All I want to do is to see which orders came from the desktop theme and which orders came from the mobile theme, so I can determine if an order came from the desktop site or the mobile site.
Is there a way to save the name of the theme as a custom attribute or flag when an order is placed?
