Sketching on "plane normal" side or "plane normal-1" in SW

Hello guys,
I'm trying to find a comfortable way of using a sketch on one or the other side of a given plane, and recognizing that "orientation" in the feature tree.

I currently create my plane using a 3d sketch (pseudo origin) , at this point, I have found no way of defining "top" or "bottom" to the plane itself

My consequent sketch will be either normal-to or normal-to_normal-to (toggle to "bottom".

If I re-edit the sketch, it defaults to normal-to, so I rename sketches with "normal-to_normal-to" orientation (+N-1 or so)

This work around works, but is error prone, and sightly tedious; I have tried to create planes "the other way around" without success. Creating views is unpractical, I mostly use this for remodeling small parts in imported files, finding the corresponding view takes more time than the above workaround.
Since features are "hidden" when re-editing a sketch, and normal-to-1 is the same as normal-to, much care must be taken.

This of course is only necessary for planes at odd angles, anything in the standard views orientation highlights in the heads up menu, then choosing the opposite view is a wiz.

I just discovered that you can build "upside down" planes if you base them on a 3d sketch drawn "through" the model in HLV mode.(I used select-convert lines) It seems to depend on the side that you draw the 3d sketch on.
Nothing distinguishes the plane, but it will normal to the "back" side.

Any other info on this would be quite welcome

I've played with this a bit, a little control is possible as follows:
Planes facing you have titles on the left side, backfacing planes on the right

When choosing references while creating planes In solid models:
- In shaded mode, planes will face outwards of the chosen part
- In HLV mode (hidden lines visible) direct selection of hidden lines (inside of a shell for example) will always face outwards
- In HLV mode,using a 3d sketch as reference on hidden lines will create a plane facing the direction from which the 3d sketch was built. This will work even with 3d points.

On surface models planes seem to only face outwards, whatever I have tried.

This does mean that you can create 2 coincident planes facing opposite ways. I'll try to play with that and see if any use can be made or if it is a useless clump of knowledge.
