ActivateWindowAndFocus - Subtitles

I want a button that will open the player settings window and then automatically move focus to control 65 (languages to download subtitles for).

I tried ActivateWindowAndFocus(playersettings,65), ActivateWindowAndFocus(playersettings,96,65) but they don't do anything but opening the window.

ActivateWindow(playersettings,language) gets me halfway there, but I need to get it to the specific button.

Is there something I am missing?

Cheers
