The component for buildmaster doesn't exist so I had to use Proget.

Currently the plugin only allows for starting a deployment at the beginning of the pipeline however that limits the usage. I would like to be able to call out a specific stage in the pipeline.
For example, if I want Jenkins to build, then have BuildMaster deploy the Integration setup, then have Jenkins run the Integration tests, then assuming the tests pass, have BuildMaster deploy to the next Stage.
Another scenario, you may want a certain deployment to a certain stage when another app is successfully, built and tested with Jenkins handling the testing.
