Little request: Render file path/dir to be saved within song

I feel a little bit annoyed about the fact that Renoise’s render file path is not saved within the song settings, but with the global settings.

Is it possible to move this to song settings, so every song can have its own default rendering path?

Just like it already is with the render file name… And if there is no default path set for a new song, it will take the last path.

Is this something that could be handled by a custom tool?

Hm if this is the case, the code would be quite short, I guess. Can you access the render path in lua and then save it as an additional song parameter?
