hey guys, I have 2 powerpoints that I need to merge.
and they both need to have custom background graphics that has been provided to me.

I am trying to find an option that lets me apply this custom background graphics to all slides but its just not there.
this is increadibly frustrating because I dont understand why it needs to be this complicated.

I have though of somehow taking this custom background and adding it to my other graphics or designs but I dont know how or see the option for it.

I have tried to find the simple command of "apply to all" but it is not there either.

can anyone please help me? I just want all slides to have the same background graphics as the first post... I have office 2007.

thank you.
