Briefcase Searching

Hi,
I need some info if this is even possible and i have seen it asked with 0
responses on the issue. I my self keep a large number of files in my
briefcase and find myself
searching in it trying to find a single file.However you cannot right click
the briefcase and have a "search" option, but yet you can start search and
select the briefcase to search in.So my question is can you add the search
function to right click on briefcase as other folders has this option.I'm not
sure if this can be done but i really don't see why not as you can search it
, but takes a few more steps to do so.
