Deleting Message

I have installed a spam filter program to my Outlook 2003
application, which filters incoming messages and transfer
possible junk messages to a special 'junk suspect'
folder. After checking for false positives, I usually
delete these messages immediately.

I'd like to know is there any way to add a clear/delete
function to the popup menu when I right-click on the
folder, just like in the Deleted Items folder? This would
save me the steps of transferring all messages to the
Deleted Items folder before actually deleting them.
Immediate deletion upon transferring to the junk suspect
folder won't do because I want to check them for false
positives. Any suggestions welcomed.
