Windows Store for Business icons in Software Center
Creating an online/offline install for an application from Wsfb should add the icon from the store to the application in SCCM / Software Center.
A custom icon can be added but unlike standard apps there is no way to extract the icon from the application.
Integrating the store icons would go a long way to polishing the end result for users.
