Sorry but you can't. Actually to do this you need to override the search on the model. Can be something like this:

def search(self, cr, uid, args, offset=0, limit=None, order=None, context=None, count=False):
    #this could have a check for this add domain based on a context value
    partner_id = self.pool.get('res.users').browse(cr, uid, uid, context=context).partner_id
    args.append(('reviewer_id','=',partner_id.id))
 return super(my_module_review, self).search(cr, uid, args, offset, limit, order, context, count)
