Automatic subfolders for speakers

How hard is it to have subfolders automatically generated for different speakers?
So in the /mp3 folder there is folders for each speakers sermons.

This would make editing later on much easier.

You can already create subdirectories based on date and selected language. Isn't that enough?

The problem with the speaker is that I don't know the speaker if the file is uploaded before the form is filled out. For date and language I can use the current date and active language as default value, for the speaker I have no such way to guess it.

No worries, I'll just use date.

Different topic, but how can I change the date field to be "0000-00-00 00:00:00", rather than automatically grabbing the current date if it is left empty?

For new sermons, SermonSpeaker assumes you want the current date for the sermon date if left empty. Most of the time this is what people use since they upload a sermon shortly after it was recorded.
If you edit an existing sermon, you can delete the sermon date to have "0000-00-00 00:00:00" as the value.

Yes, I was wondering if that feature can be disabled. At the moment I have to go back and edit half of the sermons I upload.

I have lots of old sermons with no date.

The feature can't be disabled.
Personally I would insert all those sermons and then run an SQL statement in phpMyAdmin or a similar tool: This will set the date for all sermons. If you only want to set it for specific sermons, you could unpublish those and then run a statement like this:
