From our customer Steven Ginn (email@example.com):
"In my JIRA instance, I may have customers with several accounts.
I'd like to be able to pull up tickets for all users where the reporter ~ "opswat.com"
In essence, I may be on a call or need to generate a report for open tickets reported by a customer. I know their company name is "OPSWAT" but not whether they are "opswat.com" or "opswat.net". I tried using the "Reporter Domain Name" custom field, and that gets me part of the way...but not all the way there."
