I notice that you can either get the metadata from the file or from the filename. Or at least, that the metadata in the file takes preference over that asked to retrieve from the filename.

I have hundreds of epub files where the author and title metadata in the file are messed up, but the tags and covers are the way I want.

I've used a batch file renamer to rename the files "title - author.epub" so that I can add them to Calibre using the filename, but then it doesn't get the tags and covers from the metadata in the file. I don't want to download the tags because then I'll have to spend hours editing them the way I want. Also, a lot of the covers are not found when I download the covers.

Is there a way that I can get the author and title from the filename but get any other metadata from the file when adding files to Calibre?
