Using an alternate sort selector for a bound table column?

I have a NSTableView with two columns (first name and last name) 
bound to an array. If I check the "Creates Sort Descriptor" checkbox 
for the value binding it appears to use compare: for the selector. Is 
there a way to tell the binding to use 
localizedCaseInsensitiveCompare: instead?

Or must I create the sort descriptor myself and apply it to the table 
column in awakeFromNib? Or a better solution?

Thanks,
Jim
