I recommend that you Shortcut the 'Reverse Faces' command to a key [I use Q=Reverse and Q+Alt=Orient] - with <Space.=Select - you can quickly reverse faces as you go. Alternatively you could try 2D Tools - You can draw a 'flat' 3-point Rectangle [at a preset Z-height, default=0] without a face at any orientation. In Lines, PolyLine [Curve] or Guide-Lines. There are also tools to add a face or hatching - these will face 'up' even at z=0...
