I don't think so... I have looked for this and couldn't find a way to do it.

So what I do for now is use

http://cgi2.ebay.com/aw-cgi/eBayISAPI.dll?LeaveFeedbackShow&useridto=<#SellerUserID>&useridfrom=<#BuyerUserID>&item=

Notice I left out the <#AuctionID>

I then just paste the auction number to the end of the link right before sending the email.
