Deb_A,
Okay, probably not the answer you're looking for but the most efficient way to do what I think you want is with VBA. That's how I would do it and as a matter of fact, I already some some macros that could be adopted to your needs. I'd be happy to help you with that.
However, I'm still trying to get a handle on your needs. What exactly do you mean when you say you need to "recreate the mpp over time"? I thought you already have the template, the one you so arduously created last weekend. Are more tasks being added to the individual worksheets such that you have to periodically update the template?
Just as an aside, if the program manager has bought into Project as the application to use for scheduling, doesn't it make sense to invest in training to convert the functional managers and wean them away from Excel as a scheduling tool? I know, not your hill to climb.
