Boxset only sort order

[FrostByte 5392]

Is there a way to force the order of a particular movie within a boxset only? For instance The Matrix and Underworld both have prequels and it would be nice to see them listed in the order which makes sense for viewing. However, I don't want to mess with how they are displayed alphabetically (I.e. Animatrix when looking at the whole library would still be listed under the A's) in the web client so the sort name doesn't seem to fit the bill for what I'm looking for.

Thanks
