Our game uses a UIScaler control at its tree root to handle resolution independence. We can emulate this in studio by adding a scaler to the root of every xaml being iterated on. However, this is a poor workflow as it requires the designer to remember to add and remove before submission. As such we would like an option to inform studio to use a UIScaler for layout and testing which is not saved in each xaml for our game.

Per email from Jesus

"best way is exposing a section in the project file (.noesis) indicating a node (in XAML syntax, so node plus properties) that will be used as the root of the tree. That way, you can inject a custom root node for every view in Studio."
