We use a service account for all of our automation for Oracle EPM.  Unlike an Essbase connector, each EPM application requires its own connection setup.  Due to our internal policies, we require password resets which require us to go into every connection and update the password.  With both Prod and Test environments for our EPM application, we have a lot of connections that require to be updated.  Would be a time saver as well as prevent failed jobs if there was a way to be able to have variables set up at a global level that can span Workspaces and be leveraged on connections.
