Don't create Run Configurations for certain Subprojects

Currently, when you open a new SUBDIRS project in Qt Creator and click the "Configure Project" button in the bottom-right corner, a Run Configuration is created for every Subproject.

I'd like to be able to specify for each Subproject whether it is to automatically have a Run Configuration created. (In a large project I'm working on, we need many Subprojects to produce various binaries that our main Subproject depends on, but it's rarely useful to run individual Subprojects from Qt Creator.)

I envision this being a parameter in each .pro file. For example:

CONFIG += qt_creator_omit_run_configuration

Then, when "Configure Project" is run on a new SUBDIRS project, Qt Creator will not automatically create a Run Configurations for Subprojects with that config setting.
