displaying tagged files in browser

[Tim Gray]

When I want to attach multiple files to an email message, it's 
convenient to tag all of them in the file browser, and then hit return 
to attach them all at once.  However, there's no visual indication in 
the file browser as to which files are tagged.  Is there anyway to set 
this?  I didn't see a browser_format option or anything like that in the 
manual.

Thanks
