Select Video Stream from multi-video MKV

Apologies if this has been asked before. I tried a search here, on the OpenELEC threads and Google and didn't come up with my answer:

I'm currently authoring my MKV's to contain the following streams, to reduce space on my drives and to future-proof:

- 1080p H.264 Video
- 1080p HSBS Video (for 3D)
- AC3 5.1 Audio
- MP3 2.0 Audio

In the Audio Section, it is possible to select the Audio stream as normal. No issues here.
My question is in regard to the Video stream:

I know that XBMC will output HSBS Side-by-Side, but it's fine since I can toggle the correct mode for my display.
Is it possible within the current Eden or Frodo builds to select the Video stream, similar to selecting the Audio stream on playback?

I'm hoping that I don't have to maintain 2 sets of files.

Thanks in advance!
