Dashboard Scrolling

I am trying to get a dashboard to have a particular scrolling behavior that I am not sure how to do if it is even possible.  A simple example of the ideal is below.  In this ideal dashboard the dashboard will scroll horizontally only.  The inner dashboard will individually scroll vertically.  I can not seem to get the outer dashboard to only scroll horizontally, and when it does that outer horizontal scroll turns off it appears the inner vertical scrolls.  I think I am asking for too much but was hoping to get some confirmation.  Thanks.
