Please consider adding a .Format() property to the columns for MCCB. It was a real pain to correctly format a date column of a sub template of another template. In most cases the grid control can use something like .Format("{0:dd/MM/yyy"}), but the MCCB must use template scripting. It took a while to get the scripting and escaping just right for it to work. Having a .Format() option would simplify things.
