Lock Screen Rotation for specific QML pages or programmatically lock/unlock screen orientation

There should be a way to lock the screen rotation for particular pages/screens and not just for the whole app. i.e. I should be able to lock/change the screen orientation from any QML or C++ file for however long is needed then unlock/change back when finished.

Specific example, I have a QML page for taking a picture. I need to be able to lock it to an orientation and then just rotate the icons when they rotate the phone instead of the whole gui rotating. But the rest of the app does not need to be orientation locked.
