I'm sure there are multiple ways to achieve this, but one way I've done it is to create a powerpoint with Powershell and Tabcmd that has a dashboard on each page. Then, as part of the process, we converted the PPTX to PDF.
I wrote a blog on the PPTX process, but it is a one line addition to go from there to PDF - the interopt libraries support "Save as PDF".
Hope this helps!
We'll be meeting about this sometime today, when we can test this, ill mark this as the answer; It seems like what we will need to do. Thanks.
