jql quick filter for all subtasks whose parents have subtasks I've been assigned to

[Deleted user]

I'm trying to make a quick filter that shows me just the stories I've already worked on, including new bugs that have not yet been assigned, so I would like to show any subtask whose parent has at least one subtask which was assigned to me.

any ideas?

It seems you should start eith this:

issue in issuesSubtasks("issue in issuesParents('assignee = currentUser()')")

I've tried this function, and it seems JIRA won't recognize "issuesSubtasks" or any of the functions found on this page: http://www.j-tricks.com/jqlt-subtask-functions.html. do I need to be putting my quick filter logic somewhere else?

Sorry, I forgot to say that this function is provided by free add-on AM Utils: https://marketplace.atlassian.com/plugins/ru.andreymarkelov.atlas.plugins.utils/server/overview
