In openerp same object used in different List view is it possible to change sorting order (same object) in different list view?.

For Example,

I used "patient.procedure" object in different views

In the Patient Procedure first List view sorting want to shows the order _order = "state desc, procedure_date desc

And In the Patient Procedure second List view sorting want to shows the order _order = "case_no asc, state asc"

how to shows same object in different sorting?...

I tried using inherit object but it changes affect both view...

Thanks
