Example for mapping multiple fields in a single TaskType: Map?

[sguth-affirm]

It's not clear from the examples whether or not it is possible to map multiple fields in a single Map block:

        - TaskType: Map
          SourceFields:
              - Field1
              - Field2
              - FieldN

The naming of the arguments also makes it unclear, e.g. SourceFields allows a list, but DestinationField is a singular item?
