I have a saved filter that selects issues based on a custom field (requestor) = CurrentUser() and would like to setup a subscription to send the report to each user in the custom field. However, there is not a JIRA group with all the requestors listed to include in the subscription. Most of the requestors do not have a JIRA account so jira-users can not be used. Is there a workaround or a solution where a new group could be updated dynamically whenever a new requestor is added to an issue?
