Possible to have more than one value in groupField for the groupview function?

[swells808]

I am using the group view in a data grid and I wanted to link more than one value in the groupField area. Is this possible and if so how do I do this?

Code:

view:groupview,
                groupField:'shift',
                groupFormatter:function(value,rows){
                    return 'Shift ' + value + ' - ' + rows.length + ' Item(s)';
                }

Did you ever figure this out?  I would like to do the same.
