tagnavi directory viewing?

[bassmannate]

I'm trying to do something that might be a bit unusual with tagnavi. I can't seem to find anything that addresses it so it might not even be possible.

I'm trying to organize my podcasts. As we all know, podcasts aren't always tagged very intuitively. I aggregate with Banshee and it lays everything out in directories nice and neat. I use a script to transfer them and it maintains the directory structure. Is there a way to view these subdirectories in my /PODCASTS/ folder but see the title in the tag instead of the filename like you do when you browse files? So have a menu item labeled "Podcasts" and when you go into it, it shows all the directories in it. When you go into those directories, it shows the titles instead of the filenames.

Update:

I found a bit of a work around. It's not ideal though.
I have a podcasts entry on my database menu. That pulls everything that's in the /PODCASTS/ directory. Then, I have everything sorted by filename. This works because everything has a path of /PODCASTS/SUBDIRECTORY/FILENAME. I have it strip the first 10 characters off the filename and let it display the rest. That way, I can see what podcast it is since the filenames are mostly just a string of numbers.

The downside is that it shows the rest of the path with the filename and that everything is in one long list. At least everything is grouped by subdirectory. Still poking around to see if I can get it to do it the other way though.
