@ChristianOrellana I blocked it out in stepped and quickly did a spline pass. I'm probably just going to go back to stepped to fix things and redo the spline pass.
When sliding values with the MMB pressing Ctrl will increase the sensitivity (lowering each step by 10 times) and pressing Shift will decrease the sensitivity (multiplying each step by 10)
If you want to use your own Action, you could add a Flatten step, then after the Save step add a command to jump backwards in the History to before the Flatten.
