Ability to Change the device type within the device page

I have noticed that when selecting a device type that is not assigned to "Unknown" type that I am unable to change the type within the device.   If the device is has a type of Unknown I can edit and assign it to "Physical, Virtual, etc.,"  Once the device has been assigned to a type other than an "unknown" type  I am unable to Edit the type again within the device.   As of right now I can only change a "physical" or "virtual" type by clicking on the Action dropdown selection "change device type" with the checkbox selected for the given device.

Would like for the ability to Edit the device type within the device page, despite what current device type it is assigned to.
