A little new so please forgive my ignorance! I searched and have been neck deep for hours and haven't found any info on this subject:

I have a blog with multiple writers, all have comments enabled and I want only writer A to see (in the approval queue) the comments to HIS blog and writer B to only see/approve the comments to HER blog. Right now permissions do not allow me to divide the approval queue up like that, am I missing anything?
Thanks!
