How to setup approval procedure for extended transport management system?

Hi,

We got dev and QA system in our ECC system landscape.

We got extened transport control activated between dev and qa system.

In cosolidation taget group i got 2 clients from dev and one qa golden client listed in this target group.

Havoing said that, i would like to set up approval process in such a way that before the transports released from dev golden client,they should pass the approval steps.

How would i configute that?.I was trying to search for notes or help links to help me with this task.

But i could not find anything.

Any help would be appreciated .
