does camel support custom policy for processor level ?

[ext2]

Hi:
        Camel policy is very useful to define some custom wrapper features;
But in camel 2.2 , it seems the policy only apply on the whole route; And it
cannot define a policy on a special processor, is this true?
        And does camel 2.x support some mechanism to support define custom
policy for specified processor(not the whole route)?
