How to nest conditional fields in Word Templates

In GP Report Writer we create conditional fields so the result is either true with a value or bank.  On our report, in report writer, we place all the field on top each other and set them invisible when blank/empty.  When we stacked the fields on top each other only the one field that applied would print and the others would stay hidden..  I need to recreate this in Word Templates.  I have the conditional fields created in Report Writer, but I would like to know how to use them in Word to allow the correct field to only print.  Word doesn't allow you to stack fields.

Thanks!
