I want to be able to deploy exactly the same way to multiple environments; thereby rehearsing the eventual live deployment many times per day.

Currently, all deployment tasks are local to each environment, so if I make a change in one, I either have to:

1. Go through each of my 8 environments, and make exactly the same change, which is highly error prone
2. Delete 7 of my environments and then clone them all from the one I changed, thereby losing my entire deployment history.

This could be solved either by having a set of common tasks that all deployment environments run, or by introducing task templates.
