Anchor block reference to another

[E3DE]

Hi, 

suppose we have 2 entity, block references A and B. I want to anchor block B to block A. Where block A is moved, by user command or also by an application, I want to apply same displacement to block B. What is the right way to do this?

Thank you very much.
