NetBox Napalm multiple users, passwords (one pass to rule them all)

Is there a way to define multiple napalm user/pass credentials within netbox config file? Not all devices on my network have the same username/password. I know you can call Netbox API and define custom credentials, but I need this functionality only for status of the devices on Netbox webGUI.

Part of the netbox config: #Credentials that NetBox will uses to authenticate to devices when connecting via NAPALM. NAPALM_USERNAME = 'admin' NAPALM_PASSWORD = 'admin'
