The closest I've ever seen had the ability to read the current revision from Windchill PDMLink plus used some model parameters for the rest of the information (drafter, checker, date, revision number).
I'm not sure it's possible to easily do what you're asking for.
ModelCHECK can be set up to ensure the parameters are all filled in, but that doesn't really mean the correct information will be included.
I also don't really see a way to fill in old revisions or to have the latest revision automatically create a new row in the revision table in order to keep that revision history on the fact of the drawing.
Your statement "engineering changes recorded electronically blahblahblah" makes me think that you were previously using the revision block to list every change from one revision to the next. Is that true? (Either way, can you provide a sample screen shot?)
