Hi Bryan
Is there any particular reason why you are using PowerPoint if you have to print them to pdf. Would it not be easier if you used MS Word where you could split the document into Sections and have differing numering styles in each section.
For example the first section could be the Amendments section with page numbering such as i, ii, iii, iv, v iv etc and in the section sections you would have your main document with numbering such as 1,2 3 4 5 6 7 etc.
Would this resolve your issue?
