phpstorm 4.0.3: Is it possible to set dependencies

Hi list,

i switched from intellij to phpstorm for php development. Now i wonder
if there is a way to set up a project that can use typo3_src as a
dependency for eg. typo3-extension development, so I can get
code-completion for core-classes etc ?

Any hints are welcome. I just started using PhpStorm. In IDEA I could
add a module dependency to resolve this kind of stuff.

Best regards,
Tilman
