Thank you, yes, that definitely would be the easiest solution for this example.
But I’m ultimately looking to be able scale this idea up to 11 or more different positions, and be able to move independently and seamlessly between any of the positions of keyframes 1-4, 5-1, 4-6, 7-4, 9-11, etc., using a single control interface, such as a slider. I think I might be expecting a computer to be smarter than they currently are, or maybe I need to write a discrete script for this purpose.
I’ve been looking into the Joysticks & Sliders script, which gets me a little closer to what I’d want to do, but still appears to have some limitations.
