The default shift steps can be modified to include different information than is included by standard. This can be modified by clicking on the Configure Shift Steps button in the Admin Portal.
From within here, you can then see the different shift steps that can be modified. Selecting one of these allows for the Configure Step button to appear which can then be selected.
This will open an interface that shows a very similar setup to any other step. There are however, some fields that are mandatory and can not be removed. Others can be edited or changed as required.
