Schizoaffective Disorder and premorbid functioning

Is recovery to premorbid function (with treatment) incompatible with schizoaffective disorder in the same way it would be with schizophrenia? I'm puzzling over whether I would be able to reject a historical diagnosis of schizoaffective disorder in favor of mood disorder with psychotic features in such a case.
