New Feature Problems: Vendor Returns

I searched the forum for any threads related to my issue and found none.  So either the 2007.0.5 version we're using is not the latest, or no one has come across these issues and reported them here...

First of all, I had hoped that a vendor return could be performed at the P.O. level since we generally do not hold inventory and then do a massive return to vendor.  This feature is available.

Second of all, I have had problems trying to keep track of returns in the old system because of the time it took to get the credits from the vendors.
