Have a textarea for "notes" when promoting a release to an environemnt
In our setup, TeamCity creates and deploys a package to the "Test" environment. Then upon approval, a specific package will be promoted (by a human) to higher level environments (i.e. QA and Prod).
We need to write notes when doing so. i.e. Who approved it, etc.
