Using Mailman, how to unshunt message back into hold queue for moderation?

Using Mailman, how to unshunt message back into hold queue for moderation? References How can I get Mailman to reprocess messages in a queue directory? Or alternately, how can I transfer all the messages from a queue directory into the moderation hold queue for the relevant list(s)? My problem is that my in queue directory is full of messages that previously passed moderation, but were never delivered because my qrunner wasn\'t working. I know that I could just start up the qrunner and those messages would get delivered, but I want list administrators to have a second look because some of the messages are fairly old, and it wouldn\'t make sense to send them now. I read about a Mailman command called unshunt but I don\'t think it does quite what I need here.
