Change module installation paths

Hi folks, I have transferred modules to sites/all/modules/contrib for all drupal contributed module i have used and sites/all/modules/custom for all the module i have developed. This works all well, but when i try to install a module using URL, the module gets extracted to sites/all/modules/ instead of sites/all/modules/contrib. As well as when i extract the module directly in sites/all/modules/contrib, than it doesnt present there in module listing(i.e. i am not able to enable it).

Is there is any way to install(extract) the module directly in sites/all/modules/contrib.
