I believe this version of the mobile web is just a "mobilized" version of the Web Desk. I don't believe there is a way to customize it strictly for "mobile" without modifying the Web as well. I have a feeling this will something that is up for discussion in future versions, but I believe for now -- unless anyone has done it which if they have I hope they post up here -- it's just controlled by how your Web Desk looks.
Our LANDesk support call confirmed what Jamie said in the above reply. Fingers crossed for future enhancements to the mobile web desk. Thanks Jamie.
