I have myself never heard of anything like this, if it involves contacting the bureau.
What is certainly possible is to contact the creditor (the one who is not reporting to one or more bureaus) and ask if the creditor would be willing to begin reporting your loan to the three bureaus. The answer may well be "no", but you can certainly ask.
A final note:
It's possible that in the research you did, what you actually ran across was a discussion of Regulation B of the the Equal Credit Opportunity Act. Reg B is sometimes called the “shoebox credit” provision of the ECOA.
It does not compel the credit bureaus to add a history of a well paid account to their credit file. (This is what you were asking about.)
Instead, Reg B compels a prospective lender to consider the history of that account when it is reviewing your application for credit. So, for example, if you are asking a very specific Suntrust branch in your city for an auto loan, you can bring to them proof of that account and all your payments, and they are compelled to review it and factor it into their decision.
Here is a discussion of Reg B:
