Duplicate Targets in XCode

Without resorting to Sytem Events, Is it possible to duplicate targets in XCode 4.63?

tell application “Xcode”
set myProject to project 1
set myTarget to target 1 of myProject
duplicate myTarget
end tell

Error – Targets can’t be copied

Scripting is pretty well borked in Xcode 4.x. The few things that work are a matter of luck, where the new code has coincided with the Xcode 3 dictionary. Log bugs.
