Trigger build job from deployment

Use case:

I need to run integration tests (e.g. selenium tests) after deploy on some of configured environments.

Now it is not possible.

Could you implement some trigger to run build tasks by the success release/deploy, e.g. to run selenium tests on the new release?

BTW, do you think about adopting the workflow engine (e.g. from Jira) to customize the build/deploy/test/promote process?
