Project List - Include hidden projects

Using host:8088/main/system/projectlist, I am able to get an xml list of enabled and not-hidden projects.
The xml contains a node, but only projects that are not set as hidden seem to be listed. Is there a way to include hidden projects as well?
I’ve tried appending “?hidden=true” etc to the URL but without luck.

Hi
Did you find any resolution to this? I am wanting to do the same thing.

Only enabled, launch-able projects are returned by this endpoint. There are no configuration parameters that will change this.
