So, I'm using the current version of Edge Animate (2014.0.1). With this version, the runtime that is utilized is "edge.4.1.1.min.js". I've tried using runtime "edge.5.0.0.min.js", but that seems to break my animations.
I would love to (need to) do what you've described, but unfortunately, it doesn't seem to work with my version of Edge (and there doesn't seem to be any updates as of yet - or pre-releases).
Any thoughts or additional information would be appreciated.
