Dell K1000 - Add Asset Users to Device Inventory
Because of our tracking requirements, we have an asset record for each user. That user can be assigned to any number of devices in the device asset record. In the user asset record, we have a single field of type device asset. By selecting a device asset on the user asset record, the user asset record shows up under the Related Assets section of the device inventory page. I think this is what you are looking to do.
