Is there to change the background color of an imported Power Point slide?

Hello,

I imported a few Power Point Slides and was hoping that they would take on the background color of the Master in my Captivate program.   On the slide there are only a few small circles, and in Power Point, the background is white.  WITHIN Power Point, I cannot match the background (gradient) color that I am using in my Captivate project.  As far as I know, Power Point doesnt have gradient colors.  Is there a way to change the color of my Power Point slide in Captivate_6??

Also, it would be great in the objects on imported Power Point slides still showed up as objects in Captivate that you can move around, etc!
