Using vertical and horizontal line buttons

Line > Horizontal
and
Line > Vertical

These horizontal and vertical line buttons are useful and allow us to draw them at once. But they always draw in one direction. The horizontal line button always draws from left to right and vertical draws upwards. Is it possible to reverse this as we need? It would be very useful.

Use the options in the Tool Option Bar to change this.

Ok great, I had not paid attention that this showed up in the toolbar. It also allows to change the length or snap from either end or even middle. Thanks.
