Add functionailty to split pages

We frequently get request to split files coming from eDoc Builder. We see this functionality being added to AWI or potentially eDoc Builder. Please see below for a few business cases:

1. eDoc template for Business Cards are shown on site as front and back for the user, but the backs are already printed as "masters". Only the front file is needed for printing.

2. Many vendors require files to be split into "front" and "back" files.

3. eDoc Template is two pages to create multiple products (e.g. Notecard and Envelopes) the user only has to enter information once, but the files are produced separately.
