Closed Captioning on Chromecast?

Are there any plans to add CC to Chromecast or LG? It’s the only thing holding me back from using my Tablo more and signing up for the premium plan. My partner is hard of hearing and can’t watch TV without it. I’d like to avoid having to purchase an additional device just to stream tablo.

Just as an aside, the new Google TV Chromecast device allows the Tablo Android TV app to be installed and it does support CC.

My Google tv chromecast does not show CC when casting from a remote location. When using my Android phone to start a program remotely it will allow for CC, but when I cast it to the chromecast dongle then it does not show CC.
