I recently came across your thread after doing research on the same
issue. It appears you have this functionality in Adobe LiveCycle
Designer, as mentioned above, however, it's being decommissioned. The
functionality will be available in Adobe Experience Manager, from what I
was told. Although, the purchase is not justifiable for me.After further
research, I've discovered you can create a form with this feature in
Microsoft Word using the Developer tab. See the Repeating Section
Content Control....
