JQL for subtasks that only include specific labels?

Question

Hello,

I'm trying to create a query to identify all regular issues and include subtasks that ONLY contain a specific label. Could someone provide me with an out of the box JIRA query for this? I work on a large server instance and do not have the ability to go the plugin route.

Thanks!

issuetype in standardIssueTypes() or (issuetype in subTaskIssueTypes() and labels in ("", ""))
