Filter Audio clips not synced to video (Media Pool)

Hi.

Is there a way, via a smart bin for example, to group audio clips that are NOT synced to video?

I am trying to locate a Voice Over audio clip that has been badly referenced in the script notes. If I could group all audio clips that are not synced to video, I could listen through them and find it. They shouldn't be THAT many. (I have autosynked audio clips to video using the "Auto Sync Audio" method).

Thank you.

I thought of a workaround. Make a timeline with all video clips. With such timeline active, in the media pool/list view, sort all audio clips by "Used" column. (Right click on the media pool column headers in "list view" to make the "Used" column visible). The clips that are not synced will now appear together at the top of the list.
