options to make labels of two yAxis aligned

refer to:
http://highslide.com/forum/viewtopic.php?f=9&t=7740

just like:
yAxis: [{
title: {
text: 'yAxis one'
},
opposite: false,
bindGridLine:{
to:1, //bind chart.yAxis[0] to chart.yAxis[1]
values:[100,0] //two values from chart.yAxis[0] and chart.yAxis[1]
}
},{
title: {
text: 'yAxis two'
},
opposite: true
}]
