Say, The attached word documents are needed setup in power point as follows: Each document to be exactly half height of an A4 Page and when printed to be duplicated in the lower section such that we have a 2way A5 flyer that can be cut in half. The documents to be printed back to back prior to cutting to get a double sided A5 flyer.
Ideally the "canvas" top A5 section of front and back should be easily editable for future changes. The flyer then to be duplicated in the bottom of the A4 Page.
This seems quite involved for an unskilled Word or Powerpoint user.
