As a product manager, I have included [client name] as a field on all Jira issues, so that I can easily see which tickets are of interest to a particular client. The [client name] field is a multi-select pick list that we (dev) maintain to ensure consistency. I need the ability to count the number of distinct [client name] values associated with a given issue, so that I can easily sort my AIO report to bubble issues that impact the greatest number of clients to the top. Any ideas?
