How do you set the active tracks via a chromecast receiver while media is loading?

Question

I'm developing a custom media receiver for chromecast. Is it possible to set the active tracks on media load? For example, I have two embedded audio tracks, and I want the second audio track to be what plays immediately on load. The sender does not know what embedded tracks are available, so using the LoadRequest is not an option.

Support for this was added in the 2.0.0 receiver release on Dec 1, 2014: https://developers.google.com/cast/docs/release-notes
