[Feature] Overwrite an existing configuration

[mheiss]

Scenario: Developers are checking in launch configuration into a code repository so that the entire team uses the same settings.

Now as a developer i want to customize an existing configuration to adopt some settings (xmx, plug-ins). Currently i have to derive from the existing configuration and choose a new unique name. This is annoying in the case that the configuration is referenced in a shared launch group. I would now also need to change the launch group.

Would be nice to have a feature that allows me to overwrite settings of an existing configuration. It should be validated that there can only be a single configuration that overwrites an existing configuration.
