Ability to run a deployment manually without triggering cascaded ones

 Problem

Some times is a requirement to serialize environments. The only feature that can be used for this is the After Successful Deployment trigger.
The problem with this one is that if you need to manually run one deployment, all of the cascaded ones are triggered.

Suggested solution

Provide an option in the deployment trigger where we can select if the prior deployment should be triggered manually or automatically for the actual trigger to work.
