Our template has three items in the slide master, a .jpg running down the left side, then a .jpg logo and our tag line along the bottom.

I have told we have to be able to have slides that can "turn off" the logo and tag line and only have the .jpg on the left side.

I thought I might be able to run two slide masters in a presentation and choose what master to use for each sheet, but have been unsuccessful. Is this possible?
