It's probably Arlett Vereecke, I believe her name was brought up earlier in this thread. She fits the profile slash described perfectly. She was fired by gnr/slash, not sure which one, in the late 80's.
A couple of years ago slash hired her again to be his publicist but later fired her because she had couldn't get along with Perla I believe, atleast that's what Arlett claimed.
I googled her not knowing who she really is. It seems she was somehow involved in "Live Era 87-93 as she is mentioned in the liner notes, but it does not mention what her involvement was. It also says she is an artist.
