The default row selection behaviour for the Kendo Angular grid is to toggle the selection - that is, clicking a selected (highlighted) row will deselect it (remove the highlighting), according to the [documentation](http://www.telerik.com/kendo-angular-ui/components/grid/selection/). 

I want the selected row to remain highlighted if it is clicked repeatedly. I have been unable to find anything in the documentation that would suggest that this is possible, yet it seems like a reasonable requirement (a situation in which there must always be a row selected).

Is there perhaps a built-in, undocumented way to do this?
