I've had this issue throughout many projects already: I created a number of 'chained' artboards that - as a collection - play an animated sequence using Auto-Animate and the 'Time' trigger. A loading screen or splash screen for example.

I'd love to be able to target this 'set' of animated artboards and choose a 'custom' exit point so that the final artboard points and navigates to an artboard of my choosing. This way I can re-use the same animations throughout the entire prototype without the need of duplicating (and maintaining) several instances of the same thing.
