Um, You can do that right now by having a mail filter on your outgoing mail (at least you can in OS 9, I haven't gone to OSX yet).
Go to Setup>Mail Filters and click on the little cog to set up a new filter. Give it a name. Under Conditions, choose 'status' from the left pull-down menu, then 'is' from the middle menu, then 'sent' from the right menu Under actions, choose 'move message into folder' and choose the folder. Then click 'stop applying actions to this message' I've had this set up since I started using PowerMail - I've actually got 2 sent mail folders because I have mail accounts on a couple of different domains and I want to keep the sent mail separated. Hope this helps.
