An organization user has the ability to create custom delivery methods. Under the Settings tab, located in Info, organization users can choose to Add a delivery method. Examples of what might be considered a nice use of adding a custom delivery method are if you had a "Pick up at starting point". This is limited to a specific kind of tour often times and isn't considered a default, but can be created as a custom delivery method.
Tip: You can also edit the description of the default delivery methods, although you cannot change their names.
You can title your delivery method and add a description.
