How to add @Priority annotation with different values in aspectJ

Question

I have an interface and a bunch of classes implementing that interface. I want to add @Priority(xxx) annotation to all these classes with changing value as depicted below.

public interface IMyInterface{}

Before :

public classA implements IMyInterface{}
public classB implements IMyInterface{}

What I need:

@Priority(1)
public classA implements IMyInterface{}

@Priority(2)
public classB implements IMyInterface{}

What i tried so far:

declare @type: com.package.* : @Priority(999);

I am able to add annotations with same value with above approach but i need to add different values.

Any leads on how to achieve this would be very helpful.
