Assign devices outside of user listing
I'd like to be able to restrict staff users to only see one user listing, while assigning them an asset from another user listing. They could see the asset checked out to them, but not the other assets in that user listing.

Have a look at Settings → Company Settings → Visibility → Limited to Userlistings → Allow assignment of asset to users outside their User Listing
Have the “Allow assignment…” option checked:
- admins will be able to assign any asset to any user
- supervisors will be able to assign any asset in their listing to any user
- staff users will continue to see assets that are only in their listing OR are checked out to them
