Make examples installation opt-out in Qt Maintenance Tool

I'm a long long time Qt developer and I really don't need the examples and demo when I install the SDK, but they are mandatory included in the base package, which is taking enormous amount of disk space when one have to keep several version of Qt for several targets installed a same time on the same dev machine.
What I would need is the ability to opt-in or opt-out the installation of the examples and demos for each Qt version that I install, just like any other non-essential sub-package.
