NUX Ability to Re-Size Drop Down Lists in Grids

Is there an ability to allow a user to resize a drop down list in grids?  Currently it looks like it defaults to the size of the column, and when selecting a list item within a hierarchy, often the view of the item is obstructed and you have to scroll to see the item.  We did notice that you can resize the column right before you select the list and this helps, but users often don't notice this and it would be very helpful if you could resize a list drop down after you open it.
