Correct, this has not been modified to be a Netbox "custom script" which can be directly integrated into the web UI.

OK. Great script tho. Saved me from a lot of hassle.

Do you plan to write one for UI? Would be great.

Yes, this is done, and contributed to the public "reports" repository. See:

• https://github.com/netbox-community/reports/blob/master/scripts/add_device_type_components.py
• https://github.com/netbox-community/reports/blob/master/reports/dcim-reports/missing_device_type_components.py

(for safety the update script asks you to select the device(s) to update, rather than blindly updating all devices)
