How to prevent PyCharm from creating "PyCharmMiscProject" by default?

On the first run, PyCharm always creates this placeholder project named “PyCharmMiscProject” in my home directory. I know it’s trying to be newcomer-friendly, and that there’s the “Show this page on startup” setting, but I simply don’t need this feature. How do I get it to be disabled by default so that I won’t have to delete the placeholder project every time I reset the sandbox?

I don’t want to resort to modifying permissions. Ideally, the solution should work either machine-wise or user-wise (as opposed to, say, setting a custom property in the build script).
