I'm using ArcGIS Pro v3.1.3.  

I have an existing raster, Cropland Data Layer 2014.  It has about 90 classes in its Colormap Schema.  I want to merge some classes into one.  For example, I want to merge classes Corn, Sweet Corn, and Pop/Orn Corn into one class (Corn).

The Merge Classes function does not work for existing schema.  How do I merge classes in existing colormap schema?   After merging, I need to assign the RGB values but how do I go about that?

Appreciate any help.
