arcgis desktop - Controlling page count increment of Data Driven Pages using ArcPy?

I was wondering if there is a way to add coding to Data Driven Pages with python.

I would like to be able to take the "Data Driven Page with Count" and increment the count by one or in some cases two.

For example, I have 10 data driven pages and need to add two more pages to the series i.e. making the final count 12 pages.
