[Author] in title -> unknown in Calibre

Hi,

I have a library of comics and to keep it organized I'm testing Calibre.

The problem is that the comics are in .zip with the following name:
"[Author] Title"

When I import them with Calibre , for the title I get the full text:
"[Author] Title"

and for author it says "Unknown"

Is there a way to be able to mass edit all the comics and let Calibre know that the author is inside "[Author]" and for the title ignore the "[Autor]"?

I have been trying to find the solution but I couldn't.

Thanks!
