Ability for date fields to be DD/MM/YYYY, rather than MM/DD/YYYY

[mikemitchel]

CLEO can apply this transformation on mapping, but only if the date variable is not being used within another mapping function. In addition, the Guided Pathways ask for dates in MM/DD format, but the outputs generated by the Guided Pathways provide dates in DD/MM format. This can be confusing for users.
