Automating Headers

Hello,

I currently have a PPT template that individuals fill out. At the top of each slide are the below variables, this "header" is on each slide within the PPT. I want to automate the header so that the individuals filling out the form, only needs to fill it out once and not on every slide. Is there a way to automate this so they only have to fill it out once and not fill it out on every slide?
