When used in conjunction with the "Promoted Builds Plugin" it would be very helpful to allow promotions from the "archived" location and not just the workspace.

Build/Test/Promote Logic Flow
Build Job #1, (no blocking) Archive Build Artifacts
Build Job #1, triggers Test Job #1,
Build Job #2 , (no blocking) Archive Build Artifacts
On success of Test Job #1, using the "Promoted Builds" of the Build Job #1
SCP copies files from Build Job #2 (because its form the work space)

Oops!

So by the time the promotion occurs the workspace might have been wiped and rebuilt with a new Build Artifacts . This is important because some test may require a lot of time and we dont want to block up stream builds
