Automatically assign unknown devices to a user?

Is it possible to automatically assign unknown devices to a user?
I currently have the following settings:

<entry key='database.ignoreUnknown'>false</entry>
<entry key='database.registerUnknown'>true</entry>

But I have to assign each unknown device to a user so I can see it.
Is it possible to automate this?

You can use "database.registerUnknown.defaultGroupId" parameter to assign unknown devices to a group, which can be linked to your user.

There is also "database.registerUnknown.defaultCategory" parameter in case you want to assign some category for those devices.
