solidworks origine schizzo

[hpienergy]

Good evening,
I ask if someone knows how to orientate in the opposite direction the z axis of the origin of a sketch created starting from a face and not from a plan, so that it has as reference a face.
I have seen that if the sketch is created by a plan it is enough to reverse the direction of the plan and it automatically rotates the sketch but in my case the sketch is rested on a face created earlier with an extrusion.
I tried with the align grid/origin function in sketch tools but once selected the location of the origin it is possible to select only one axis and not all two x axes and y at the same time to orientate z.
I need this to be able to see a sketch once open oriented in the right direction and to control the direction of the functions size or extrusion, when I have to make important changes in the previous functions sometimes generate mistakes that automatically turn the axes z of the sketches seeing them when opened rotated above and from inside the piece to outside instead of from outside to inside the piece.
I tried to search the forum but found nothing about it.

I don't know if I understand, maybe some images would help to understand. cmq tries to create a floor in the position you need and move the sketch to that floor.
