Adding new Layout that is usable from Eventserver and Management Client

Is there a way to create or merge a new layout and use it just like existing layouts? As in the “Management Client” via “Configuration.Instance.GetItems ()” findable and in the “Event Manager” (BackgroundPlugin) via “VideoWallSetLayoutCommand” callable.

What we need is a Layout that has 1 big window in the middle and 12 small windows around it. It’s based on the 4x4 Layout.

In the new MIP SDK 2018R1 (with release today) one of the news for the Configuration API is:

View layouts can be created and modified through the existing classes LayoutFolder and Layout.
