Calibre OPDS - Changing downloaded file naming template?

[halfsat]

Finally set up OPDS for wireless access to my Calibre library. I'm curious if there's any way to change the default naming convention of the downloaded files. It seems like they're currently downloading as {author} - {title} and it's giving me some trouble with how I have my books sorted in KOReader. When I send books via Calibre (wired), it sends them as {title} - {author}.

Is there any way to change this in OPDS to more closely match the wired send behavior? The other thing that I've noticed is that the {title} when downloaded from OPDS seems to include initial articles, while the {title} from a wired transfer uses Calibre's "Title sort" field. The sort title works better for my setup.

I did see the option to download the filename straight from the server and that gets closer to what I want, but those seem to include the articles.
