Any way to order replacement bumper covers already painted?

I backed into a pillar recently and smashed my left rear taillamp housing as well as damaged the upper and lower bumper covers. All of the damage is cosmetic but not something that can be buffed/painted.

I would like to replace the pieces myself. I have already ordered a replacement taillamp housing but all I can find for the bumper pieces are primed ready-to-paint parts, using the official GM part numbers.

Does anyone know if these pieces can be ordered in one of the existing factory paint colors?

I'm looking specifically for these,
Upper Bumper Cover, rear, GM Part #23369766
Lower Bumper Cover, rear, GM Part #23369767

Thanks.
