Extruded surface must be normal to sketch plane?

Hi,

When testing "extruded surface" feature, I found that the direciton of extrusion is always normal to the surface. For example if I define the sketch profile in plane "Front", the extruded surface is always normal to "Front".

Is there a way to change this, such as specifying an arbitrary path and let the sketched profile to pass through that path and form a surface during this course?
