In Calibre, is there a way to do an "Add books from directory", but only process selected (or one) format?

If I have a directory with both EPUB and MOBI files, I don't want to convert MOBI files to my default format (EPUB), I just want the Add to skip books that aren't EPUBs. I can't see a way of doing this.

I know that in the "Automatic Add" I can specify file extensions to ignore, but it looks like Auto add doesn't support sub-directories.

Am I missing something?

Thanks!
