Add a dropdown selector for switching between multiple RMS sites

Some organizations manage multiple Configuration Manager sites with unique RMS instances for each site. It can be time consuming to manually update the RMS URL value in their RCT configuration each time they connect to a different Configuration Manager site.

If we added a drop down where users could add RMS URI options to more easily switch between RMS instances, it would save time for users in this scenario.

PowerShell script attached to demonstrate suggested functionality.
