Please show devices position from both sides(font & back) in DC Visualization

Please show devices position from both sides(font & back) in DC Visualization. and make it configurable.
Right now, i can only configure the orientation out of (front, back, middle) please add a 'front & back ’ or both option.
Compared with GLPI, it will show on both sides. please change this, i really like ralph, more. Don’t make me switch to GLPI.
