function to get cell by column id

If i want to get a cell by column id i have to do the following

var holidayNameIndex = xon.reports.grid.getColIndexById('holidayName'); grid.cells(rowId,holidayNameIndex );

It would make more sense to just do

grid.cellByColId(rowId,'holidayName');

Would it be possible to add the folowing code to dhtmlx so it can be done

dhtmlXGridObject.prototype.cellByColId = function (rowId,columnId) { var index = this.getColIndexById(columnId) return this.cells(rowId,index); }

I have got the following in my code to add this function until dhtmlx add it (I hope)

if(dhtmlXGridObject.prototype.cellByColId == null) { dhtmlXGridObject.prototype.cellByColId = function (rowId,columnId) { var index = this.getColIndexById(columnId) return this.cells(rowId,index); } }
