Draft direction and Neutral Plane

I wanted to create a part which is 22° orientated to the draft direction. When I select a neutral plane the draft will be done normal to that plane? What about the case I want to select a neutral surface that is not planar?

You can only create a sketch on a flat face.
If it is non-planar you will need to construct a plane first before creating your sketch.
to make it a little bit more clear, please have a look at following simple example:

It is only one feature of a small plastic part I wanted to create last week. As You see the part is extruded between to parallel planes with an angle of 22° degrees to the top plane. The part should have a draft of 0.5° normal to the top plane (see direction arrow) as main draft direction (there are additional features that call for this direction!) with the upper plane as neutral plane. I am not able to draft the part in Onshape in that manner.
What if the upper surface would not be planar and also should be the neutral surface for draft?
I am primarily working for automotive industry where draft directions are often set, and adjacent surfaces or parting (neutral) elements for drafts are non planar.
Thanks in advance for answering.

I wrote my question in the category "IMPROVEMENT REQUESTS" because I am shure, that it is actually not possible to draft parts in Onshape as mentioned above.
So my article would better be moved to the correct category.
