Hello Erin, TLDR: My response is not how to make Cvent do it automatically, although it may be possible with the API and a custom contact field for Region.
We do a similar thing with school Districts and Regions of the state.
Cvent is weak on relationships across contacts. There is not an easy way to automate it within Cvent. And I'm not sure if the fields you need are accessible using the API and a script. If so, that would be one route.
If this is an annual conference, (i.e., something you need to know only occasionally), a simple way is to handle it externally, outside of Cvent.
The factor to consider is how often do you need to run and share the report?
I assume you are collecting a County field during registration and can report on that.
Then make a table in Excel with the columns County and Region, then use merge or lookup/match to populate the Region for each person. Share the resulting Excel report with those who need to see it.
I have a script that I run to do this for me in seconds. But it is external, so if the info in Cvent changes, of course, I must export again and re-run the script. But this is for a report that I don't need to run every day, so not a big deal.
To do it internally, inside Cvent, you can make a custom contact field to store the Region. (This solution is still not automatic, but helpful because it is now being stored in Cvent.) Run the above lookup/merge Excel report to get the Region for each person, then bulk import it into your Contacts custom field. The custom contact field is usable inside an Event Report.
The downside is that you will have to update it for new Contacts (but you can easily see who is missing Region info), and you'll have to double-check it occasionally as contacts move and change Counties but the Region field will not change automatically; you'll have to make the changes either manually or bulk import.
oh! added idea: a custom contact field that you use during registration: Instead of the standard County field, let registrants choose from the drop-down of custom county field that already has the region attached to it, like "1-Brown, "2a-Kane". The registrants won't care what the number part means, they just choose the county name. This would report sorted by Region. Or if you do the County first, "Brown (1), Kane (2a), it would sort by County. You could have both ways in 2 custom fields and ask people to select it twice during registration, which may be too silly. But again, you can always manipulate the exported report outside of Cvent and slice the Region and County into 2 columns.
