WSO2 Greg Property Handler

Question

I need to copy a resource collection to another

Registry.copy method works perfectly for this

Now I've to implement a kind of merge and i'm dealing with this constraint :

Only the new properties must be copied from source to target

Is it possible handle this condition using Handler ?
