I was very poor at this during my instrument training.
My solution, which worked, was to take a digital photograph of the instrument panel, then go and label it with the various scans ON THAT AEROPLANE, and spend time just rehearsing the scan using the piece of paper.
It worked for me, and would be as easy for anybody else to do. I think that it worked particularly well because I produced it for myself, rather than having an instructors version imposed on me.
