Hello. Is there a way a change requester can approve and move a change to the next stage?

After the technician has sent the requirirements definition to the requester, I would like the requester to be able to aknowledge the correctness of the analisys so as to move the change to the implementation stage.

 It would sound a little bit like the current ability for a user to close a request that was put in resolved stage by the techinician.,

Thank you,

Federico.
