Matrix: expand entire row single button

[sasdfasdfsad]

When using a Matrix, is it possible to make it so only specific columns have the +/- expand / collapse buttons?  

I want State and City to show +/- but the rest (customer name, address, notes,etc) to not give the option to expand or collapse.
