Be very careful with this. If you attempt to adjust overall outside or inside softness with a Bezier shape, the softness will tend to "pop" to a specific level all around the shape, which is disastrous if the softness shape is precisely keyframed around a given object or face.
Still another approach is to keep the power window in its own node, then add another separate node to blur it, and then feed the key output to the correction node.
That would be another way, but I don't think it will save time or provide any more flexibility. The window still has to be tracked, moved, shaped, and the edges blurred, and the same problems will exist whether it's an Alpha Key or whether it's just in one node.
It is interesting to note that the windows in Fusion behave differently, and in some cases, they're more precise and more logical (and I think the drawing tools are easier to deal with).
