Moderator Deletion of post, not entire thread

[GrandAmGuru]

On my forum I have it setup where my moderators cannot delete entire threads (had a problem with some important ones being deleted), so we disabled their thread deletion privlages. Now they move problem threads to a holding area for us to review. Well, not all threads need to be removed, just a few posts here and there. Is there a hack that can allow individual post deletions but not entire thread deletions? Any help or clarification would be greatly appreciated.

Thanks,
