OMG - HELP!

I work for an Electrical sub. on a large project. Architecture has asked (required) all of us to match sheet layouts. So A-101 looks like E-101 and S-101 and so forth. How do I do that with almost 1,000 sheets?

I have looked and I am not seeing anything that closely resembles this issue. Are we alone in this? Any help is greatly appreciated.

Thanks
Jonathan
