Yes, this would be great… +1!
Currently, a workaround is to create these groupings in the CRM with a combination of a custom Property and Workflows.
E.g. I to group all DACH Countries (Germany, Austria, Switzerland) in a Report, I would have to
1. create a Custom Dropdown Property called sth like “Territory/Region” with DACH as one option (and e.g. North America, Asia/Pacific, etc.) AND
2. create a Workflow to assign the Territory/Region = DACH value to all Deals where Country/Region is any of Germany or Austria or Switzerland.
3. Use the “Territory/Region” Property instead of the “Country/Region” Property in my Reports
While this approach is certainly doable, it only makes sense for long-term analysis and not ad-hoc reporting / grouping where I do not want to create various properties cluttering my CRM data…
