You can manually add lines to an enhanced custom column grid.
A grid line that is added to an existing grid can be either a primary grid line or a secondary grid line. A primary line fits into the numbering/lettering order of the existing lines, whereas a secondary line is a compound of the primary grid number and the secondary grid number.
Adding primary and secondary grid line
Note: When you add a grid line before the first line of the grid or after the last line of the grid, the endpoints of the intersecting grid lines are extended automatically to the new line. Non-intersecting grid lines will not be affected.
