How to override the Apple Watch button back to go to the root controller

Question

I am trying to push multiple WKInterfaceControllers

Route: A → B → C → D

I want controller D to have a back button A.

How to override the upper left button on the watch so that I can return to the root controller?

I do not know how to access the button or override the method. All I know is that the code below goes back to the root.

self.popToRootController(); 

Answer 1

From everyone I spoke to, this is not possible at this time.

Answer 2

This is not possible, but you can do it using the IBAction written below the button
[self pushControllerWithName:@"D" context:nil];
