Where are the horizontal and vertical guides in the graphical display?

The manual shows you can set 1D guide lines in the sub-datum menu but in my subdatum menu I only see options for points and hole patterns. This is the manual page I am referring to (at the bottom): https://www.touchdro.com/resources/dro-manual/graphical-view-display.html

Found that if you long hold in the graphical display field it will let you add a guide.
