You can certainly write some code to achieve this using Open Xml sdk for Powerpoint. But the simplest way to do this programatically is to use Presentation Builder a nice wrapper around open xml to work with powerpoint presentations.

Create a powerpoint presentation file with a single blank slide. Use Presentation builder to append it to all your files. Watch this video to get started.

Hope this helps.
