RampToLevels in scenes without changing state

I’m trying to scenes to adjust the “ramp to” levels of a dimmer (mostly Cooper 9540’s) without changing the on/off state (e.g. So the hallway light will go to 25% when manually toggled in the middle of the night)

Playing with Advanced Settings in the scene, it seems like this should be the difference in “StartRampToLevel” and “SetRampLevel”, however they seem to have the same effect of immediately setting the dimmer on at the target level.

Is my intuition correct and am just being foiled by a vendor’s interpretation? Is there another way to achieve this? The only alternative I can think of is a triggered scene “when turned on”, but that would require the Vera to respond with a new level faster than the ramp rate to avoid a “bounce” in the light level.
