The idea to use special filter is a good one, but as others stated the 'top bar' isn't a real thing in email. Maybe some sort of IMAP extension, but it's a bit like asking how to put onenote into a Google doc - you might find some workaround but you are looking at two different things. I don't use those folders, I also don't use a local email client these days...
