The custom parcels are currently managed through the database. We need to provide the customer with a way to manage their own custom parcel to remove administration cost on Fastway.

• Ideally, the setting will be on the Preference page to combine all settings in one place
• Customer will be able to add new custom parcels
• Customer will be able to remove custom parcels
