Combine to powerpoints slide by slide? : I'm trying to find a way to combine two big powerpoints slide by slide:
PPT1: slide 1A - slide 2A - slide 3A - ... slide 100A
PPT2: slide 1B - slide 2B - slide 3B - ... slide 100B

--> PPT Merged: Slide 1A - Slide 1B - Slide 2A - Slide 2B - ...

To be honest, I have no clue on how to tackle this yet, any help is highly appreciated!

Thanks
