Adding Accessory Buttons To Dash?

[timmerk]

Has anyone added accessory buttons to the area between the two power outlets on the dash on NNBS trucks? I know the higher trim levels have four buttons that go in that area, so I was wondering if anyone sells accessory buttons that can fit in the same place, or if anyone knows the GM part numbers for those buttons?

 

Thanks!

I think you have to replace that entire switch panel if you want to add more switches in there.... not sure though.
