Renaming a Build Target or Creating a copy of a Build Target reimports the entire project

Simply renaming a Build Target causes all of the time savings of incremental building to be lost. In our case, a build will go from < 1 hour to 8+ hours as a result.

Further, when cloning a Build Target and changing no settings the same behaviour is observed.

Is this by design and are there any plans to remove the overhead and allow duplicated of Build Targets to take the same amount of time as Rebuilding the source Build Target.

There are a number of implications relating to this that impact our ability to collaboratively use UCB.
