I'm pretty good at Excel but not so much at Powerpoint. I'm trying to figure out how to create a textbox on one slide and to link text boxes on other slides so that if I update the first text box text, all the others have the same text.

The purpose is to edit the "last updated" date on slide 6 of my presentation and then all the "last updated" dates on the rest of the 60 slides will automatically have the same date as I wrote in slide 6.



I also don't want to use master slides.
