I am creating new powerpoint presentations every week and each slide is duplicated at least twice, sometimes three times. At the moment, I am using a template I built that has all the transitions in place, fonts, positioning etc but the text is effectively being copied in a number of different places. I'm hoping to automate this as much as possible.

For instance, let's say the text on Slide 6 always appears on Slide 25 and Slide 38, I'd like whatever I paste into the textbox on Slide 6 to automatically populate into the textboxes on Slides 25 & 38. Is this possible? Using Powerpoint Home/Student 2010.
