Two strings for the caption?

[aka Rubén Gómez]

Hello!

Is there any option to have a 2 string caption? That's my configuration:
caption always
caption string "%{Bk}%-w%{kB}%n %t%{-}%+w      %=| %0c | %Y-%m-%d "

And when I have more than 12 windows opened, I have no datetime and I
don't see in which window I am. It's not a big issue, but I would
prefer to see all my windows instead of doing ^a " to list them all. I
think that with two caption string will be perfect. Any idea?

Thanks!
