My org uses "State and Country Picklists" and I've been asked if it's possible add additional fields to the object so we can align each country to a region, sub-region and cluster and the ISO 3 digit country code.
For example: Madagascar = Country Code: 450, Region: CEMEA, Sub-Region: SSA, Cluster: East Africa... To do this, I would need to add 4 new fields to the "State and Country Picklists" so that I could assign each country the proper regional values. Is it possible to add custom fields to the "State and Country Picklists"?
