I wonder if I can extrude a volume between 2 different sketch each with same number of vertices.

Imagine the T character, 2 sketch of it where the difference is the size of the upper horizontal bar. A volume extrude from one sketch and ending to the other, looking in 3D the upper horizontal bar would be shrinking.

Is this already do-able ? If so I am failing to figure it out from the documentation. Also I would this to extend to more than 2, in fact an arbitrary number. Only constraint is that each sketch has the same number of vertices and that you can pair vertices between each sketch (each vertices in in sketch n paired with a vertices in sketch n+1).

This would allow fully parametric complex surface and volume.
