The echo step is a new workflow step type that will allow admins to run one or multiple steps in the workflow for each value entered in a multi-select field or a table.

For example, if you have a data lookup multi-select gadget on your form pointing to departments, you can now route to each department selected.
This step can also run parallel routes based on the fields selected on the form. For example, you could have it run for each expense added to an expense report in a table.
