Approve Workflow

Is there possibility to make dependency rules (or build chains) to not run deploy build unless several users manually approve deploy.

So workflow looks like:

1. Developers are preparing release branch

2. Some run start deploy.

3. Step 2 depends on 3 parallels builds that need to enter password from approve users. And build are not able to continue unless approved. 

4. After all users enter their password deploy build are continues.
