Copy/move to latest folder?

I want Hazel to automatically move or copy raw podcast audio files from an SD card to the latest podcast-episode folder in my projects folder. But I'm running into problems with the destination folder.
I would be happy if I could simply set "Sort into subfolder" to "Latest subfolder" or something like that.
Here's what the process would look like.
I have an "Audio Editing" folder. In it, I make a subfolder for each episode of my podcast (for example, tap291, tap292, tap293, and so on). I need Hazel to put the files into whatever folder is the most recently created (though I would be happy with more intelligence, like "highest number").
It seems the "Sort into Subfolder" option only works for creating new folders with text from different attributes. It doesn't seem to let me match an existing folder with certain attributes. (The "…" looked like it is supposed to help with this, but it doesn't seem to make any difference.)
Is that possible? If so, how can I do that?
