Chrome front and painted rear bumper?

[Toro]

Does anyone know if it was possible to have a chrome front bumper and painted bumper on the rear on Blazers from the factory? If so, should be RPO for chrome front, and no mention of the rear on the SPID (would indicate painted bumper). I've seen this frequently on the truck side where only chrome front is listed, and painted step bumper was added at the dealer. Just curious if that was a combo that ever occured on the Blazer side. Thanks.
