Tabris UI: Support destroying of pages in the stack

Consider the following use case:

I have a choices between {A, B, C} on a ChoicePage

When I select A, I have a sub choices between {A.a, A.b} on a SubChoicesPage

When I select A.a I see these details on a DetailsPage

When I navigate back, I want to be back to the ChoicePage and not bother with the SubChoicesPage

Tabris UI currently only supports closing of active pages. On iOS this behaviour always includes a close animation, which looks strange.

Please include an API that allows me to destroy inactive pages from the stack.
