Template Stacking with Different Signing Orders

Hello,

We are trying to stack 3 different templates in one envelope with each template having a different signing order.

Template 1: Officer, Member, Internal Dept

Template 2: VP Officer, Member

Template 3: Member, Internal Dept

When reviewing prior to sending these docs in one envelope, the signing order is duplicating the Internal Dept. Is there a way to avoid duplicates in these cases?

Thanks!
