You are right, but since no one responded, I thought that the question was silly. But here it goes.
I had to put this site in UTM coordinates, so after failing some times trying to put the coordinates in a rectangular shape....
1- I put one ref line from the left and gave the W coordinate, pushed down another ref line and gave it the S coordinate, used the coordinate dimension tool to mark the point and did the same for the other 3 points.
