Complex Animation Position

Hi.

Would it be possible to add a slider (with option to upgrade to formula) in complex animation that would allow us to tell KLWP which position within the animation we want to display?

For example, I could use the mi(pos) formula in this option to animate an overlap group to different points on the screen based on how long the song has been playing. If I paused the music playback at 47% then the complex animation would also pause at 47%, etc.

Thanks!
