I think it would be very useful if when selecting a build specification, you could build all the dependencies of that build in a manner similar to the way "make" works.
When building complicated projects, there may be several builds. The simplest example is an application installer that depends on the the application to be built first. Another example is a suite of compiled utilities that all have to be compiled before the installer is made. Another example is an application that uses packed libraries, all of which should be built prior to making the final build and then the installer build.
"Make" is an old tool that does this dependency checking for you. If you select the installer to build, it would check the dependencies of the installer, defined in a "makefile", and then build any project that is out of date. The out of date projects are those where the last modified date of the source code is later then the last modified date of the built file.
In this way you can simply ask that the installer be made, confident that "make" would find all the required dependencies and compile them as well.
This can be baked into LabVIEW. The installer build already knows which build specification it is dependent on.
Below is an idea of where this feature would be implemented.
