would be great to have a predefined lists in Manage Jenkins -> Configure System.

And when you create a Extended choice parameter to select predefined list as source.

I found a work around to have one job which creates config1.properties, config2.properties and then use parameter
"Property File:" = http://<jenkins_url>/job/<configuration_job_name>/lastSuccessfulBuild/artifact/config1.properties
"Property Key:" = list

Here is similar plugin with such functionality, but I could configure it (it is old code base last upadte Dec 08, 2013)

Feature "Global Choice Provider"

Please, let me know if such feature request make sense.

Here is a Use Case:
We use it to provide a list with server names and we have a lot of jobs.
If I want to add one new server then I need to edit all the jobs.

If this feature is implemented I could change only the global configuration.

Also is there a way to export the default value list so I can use it later in build phase of the job as environment variable?
