Adding a new Blitz Actions Custom Field is as easy as adding any other custom field. Just go to Administration -> Custom Fields -> Add Custom Field and select the Blitz Actions Custom Field from the list and follow the on-screen instructions.
Adding Actions
After you have added the custom field, it's time to add some actions. From the Custom Fields screen, select Configure for the Blitz Action custom field.
To manage the actions for a given context, click the Edit Buttons link from the configuration screen.
You will be presented with a screen similar to other option-based custom fields.
Here you can add new actions, delete existing actions and reorder them to suit your needs.
