What is the format to designate a specific contact for all regions where we need to fill out our contacts under the co-sell contacts template?
If a contact covers more than one country or region, enter each of the two-letter codes, separated by a comma (for example, US, CA, FR). If a contact covers all countries and regions, use the three-letter code OOO.
