pub fold. clndr:Author can't delete items created by self ..

I have a shared vacation calender in a public folder. Employees have author
access only (can add/view/edit/delete their own items but not others). A
supervisor, who has owner access, can of course modify anything. Works fine.
Employees can add/delete their own stuff.
I wanted the supervisor to have to approve all the requests, so I
enabled moderation. Worked great. Except, now since the moderator
approves/drags the request (and why can't their just be an approve
button?!?!), this individual becomes the owner of the calender item. Now the
employee can no longer delete the items they add to the calender. Is there a
fix for this?

Setup:
ex2k3 w/ sp2
outlook 2k3 w/ sp2.
w2k3 R2 w/ sp1

Thanks!
