Does the preview feature not support nested folders?

The preview feature (email dev) does not pick up emails in nested folders, i.e emails/foo/bar.tsx instead of just emails/bar.tsx

I would like to know that too. I am using react-mail for creating mails for several projects and right now I have to prefix the filenames. It would be nice to be able to organize them into folders instead :)
