Yes, you can! When you first launch the Desktop Client it will detect any VR games already installed on that PC. You can quickly add these games directly onto your stations.
To do this, launch SpringboardVR AND SteamVR to make sure the content on your computer has been detected properly.
Then go to the “Games” tab in your SpringboardVR Operator Panel and click the green “Quick Add Games” button at the top of the screen.
A list of auto-discovered content will appear. Some content may not be recognized and will need to be added manually.
Click the grey "Add Game" next to the game you wish to add. That title has now been added to your library and you can begin assigning it to your stations!
