Any outcome that’s been set on a device can be reverted using the Reset option 
available on the outcome wheel. If no outcome has been set on a device, clicking the Reset option simply closes the outcome wheel.
📓 - When a reset is performed on Virtual Devices, it is deleted from the floor map and the details of the device are removed from the Master Lookup table.
To reset a device recommended by DSM and manually add a new device see Recommending a Device from Device Selection Matrix.
