To add a new mode to xrandr you have to do it manually with a step with
cvt.
Choose your mode and made the mode calculate by cvt.
Then create the mode to xrandr by adding a part of the result from cvt
and finally add it to an ouptut.
Mine with 1920x1080:
>cvt 1920 1080
# 1920x1080 59.96 Hz (CVT 2.07M9) hsync: 67.16 kHz; pclk: 173.00 MHz
Modeline "1920x1080_60.00"  173.00  1920 2048 2248 2576  1080 1083 1088
1120 -hsync +vsync

>xrandr --newmode "1920x1080_60.00"  173.00  1920 2048 2248 2576  1080
1083 1088 1120 -hsync +vsync

>xrandr --addmode VGA1 "1920x1080_60.00"

then you should have it in your widget, I hope.

Cheers,
Ted
