Custom Template

Hi.

I am trying to copying a custom "template" to my system.  I just need to slide colors and layout.  I am unable to access the AppData folder that I've been reading about because IT has it blocked out.

The slide contains custom colors and a logo that is used throughout the story.

I do, however, have the project that contains the slide that I need.  How can I copy this Master Slide over from the project into my own slide designs selections.

Thanks so much for your help!
