Thanks for the headups on memberitem. Unfortunately, that field is not accessible from the sales order item sublist which the picking ticket refers to. Our ultimate solution was to a add a custom field to the SO item sublist that defaults to true. The kit members that appear in the ticket will automagically have a value of false. If a member item is specified standalone on the SO, it will be set to true. Now we can apply logic using a FreeMarker if statement referencing the custom field.
