Feature request: SSH override

As administrator you can override many options in the client's subscription. One thing I miss is the SSH access. I would not give bash access to the normal user. As web designer I would like to run drush (Drupal's command line management tool) logged in as the user. When I want to do this type of maintenance I would like to temporary change SSH access to permit bash, login as the user, do my work, logout and reset to the subscription's value. That way all work is done with the right file ownership. Could this SSH override be added?
