Mark a folder as a 'sent' folder?

Mark a folder as a 'sent' folder?

This is related to the comment I made in another thread regarding wanting control of which columns are displayed and basically wanted to know if a folder could be 'marked' as a 'sent' folder? That way it would display the 'To' address rather than the 'From' address. I have several folders which are copies of 'sent folders where this would be useful.

Thanks

Dave
