Using workflow to populate multivalue index field group.   With each iteration of the workflow I want to add a value to the next open value in each field in a group so they are all associated properly.   On the first iteration the fields populate perfectly.  On the second and subsequent iterations, workflow populates the first field  in the second group, but skips to a new grouping (now 3rd) for the second value???   When assigning field values, you have options to "replace" or "append" (or "clear") the field value.  I select append, wanting it to place the value into the next "open" spot on that multivalue field.  Any ideas on how to keep it from skipping over as that confuses the logic behind the groups in the first place.
