There is a monthly .ppt presentation that receives new inputs every month. There are 8 different people that send me each 10-15 slides each, and I deposit all of their inputs into my master .ppt presentation.

The problem is, whenever I copy and paste or drag and drop the inputs over to the master .ppt, it creates a new, master slide behind the scenes for each slide. This creates a nightmare trying to match up all the different footers and headers and page number indicators just right.

Is there anyway to have inputted slides automagically gain the same master slide to make everything uniform?
