Apply Multiple Slide Masters to PowerPoint

All pressies contain at least one SLIDE MASTER - idea is to make universal style changes that apply to every slide.

View -> Master -> Slide Master (ALT-VM)

Right click the slide master you want to copy. Copy and PASTE.

Now you have copied and pasted all the SLIDE MASTERs, the next phase is to copy slides across and associate those slides with slide masters.

Now for the TRICKY PART.....

Right click on a slide and select Slide Design. Right Click on a prototype slide in the Slide Design window and click "Apply to Selected Slide". Boombah!
