Admittedly I haven't have much time to focus on this side project. With time in between projects I did add the option of a compounding multi-selection. Instead of selecting individual elements (as seen in previous post Make Any MicroStrategy Visualization Play Motion), this option selects and adds to the list of elements.
This should fit a different series of use cases. I have also recently seen a lot of other methods to implement play motion! It's great to see the community continue to expand on functionality.
