I want to change Profile Default Display to a App View (HWDmediashare App which shows videos) for specific profile type (Channel Profile which defines users who have videos)

User can already can click on "Media" option which is like:

- About
- Timeline
- Media

Of course I can change it's order, but what I want is, changing default display to spesific app layout.

I can check user's profile type and add some customization for using your API. But I couldn't find where can change default view layout.

Can you point me which code to edit?
Thanks
