I just needed something like this, so I made a simple animation scrubber. Could easily just update the current time OnInspectorGUI if you make custom inspector for it, but I had no need for that part.
I am sure the code can be optimized, but I didn't bother tbh.
Note: I am using OdinInspector for the PropertyRange attribute, but you can achieve the same dynamic range with a custom inspector.
Let me know if it helps 🙂
