Set Update Manager to install to sites/all/modules/contrib? I am able to use Update Manager to install new modules, instead of having to manually upload them. I previously put everything in sites/all/modules, but now have reorganized my modules into sites/all/modules/contrib and sites/all/modules/custom (for the modules I write or modify).

However, Update Manager is still installing new modules in sites/all/modules. Is it possible to tell Update Manager to install new modules in sites/all/modules/contrib instead? I looked for a setting somewhere, but can't find one (D7).
To circumvent these (and other) issues, I typically use the Drush command line utility to install and update new modules instead of the Update Manager.

For instance:

drush dl views --destination='sites/all/modules/contrib' # Download views to this path
drush dl uuid --destination='sites/all/modules/contrib' --select # Select other releases
drush en views views_ui  # Enable Views and Views UI
drush up ctools          # Update CTools


Drush also provides a number of other useful commands, and integrates very nicely with other modules. I highly recommend looking into using it if you haven't already!
