#16 Save threads by thread name, not only by thread number?

[Anonymous]

I want to save threads as folders.
Currently I save them as "/threads/%n".
But want to save threads by thread name, not only by thread number.
If you download whole boards, only a thread number is not enough to know what's inside the folder.
Are there other formatting expressions than %b, %h, and %n?
I need an expression like %threadname.
