Grep in a specific file in an archive

Hi all,

I need to do a grep in a specific file inside multiple (tar.gz) archives.

I know zgrep can grep in an archive, but as far as I know, I can't supply a specific filename from inside the archive to grep in.

Is there any other way do to this, besides extracting it and then prerforming the grep?

Thanks
