OK, worked it out. Apologies for creating noise in the forum. Maybe it helps someone else down the road. The easier solution is to create one vector in the color node for the shape. Then in a second vector do the HSL key and color correct. Enable the External Vector and select the previous vector with the 'Add' operation. That combines the inside shape with the HSL key. And it's all contained inside the color node, just spread across two vectors. But that's manageable in terms of timeline propagation.
