If you want to have that (or any other) info on your credit report, you need to go through the lender because they are the only ones from whom the reporting agency will accept the data. Contact the lender and determine whether they report their data. If they don't, there's not much you can do. But if they do, make a special request for them to verify the reporting of your info.
Also, remember that there's a time delay in reporting, and it varies by lender.
Good luck with this.
