Once you have launched the Daily Email Report application, navigate to the Manage Custom Fields tab to create new custom fields for your reports. Enter a name for the field and select Add Custom Field to save it.
Once your field is created, go to the Custom Field Entry tab to assign a value to it. Select the custom field you want to update, enter your value in the Value box, and choose the date you want it applied to — by default this is set to the current day. When you're ready, select Submit Entry to post it. You can also view recent entries on the right side of the screen.
