Edit motion paths

This is becoming an increasingly problematic issue for me. I am using multiple motion paths in my Story, and besides not having the ability to specify start and end points, size or rotation options when adding motion to items (which I have submitted as a feature request), I am unable to distinguish between two motion paths applied to the same item. I want to add a motion to move an item in one direction when the slide timeline starts, and then to move it back to its original position when a button is clicked. I have the option of reversing the motion path (after duplicating it), but then I am unable to assign it to the item as there is no way to see the paths I have created. Clicking on the item will only show me one motion path, and not all the paths that I have created for it.

The only way I have found to work around this is to duplicate the whole slide, and then create the duplicated slide as the "mirror image" for the reverse motion. This is a completely ridiculous workaround, as there is no way for me to judge where the first motion ended so that I can start the "mirror" in the same place and have it reverse.

As someone who loves Storyline, I am becoming increasingly frustrated with this limitation and the fact that I  have seen people requesting this ability for over 2 years now. I can use very basic editors and have the ability to specify exactly where I want an item to start on the X and Y axis and also exactly where I want it to stop. I honestly hope that this issue will be addressed soon as I believe it to be a core functionality to any e-Learning compiler. Motion and animation are at the very heart of Instructional Design principles these days. I was very excited about the launch of Articulate 360, but I have been underwhelmed by the new features and additions thus far. Lots of bells and whistles mean absolutely nothing when the basic functionality you expect from a compiler is lacking.
