Creating new layout using arcpy.mp in ArcGIS Pro

Our team uses arcpy.mp to automate production of large volumes of maps. We have created an ArcGIS Pro project which contains several commonly-used map templates (as layout objects), such that team members can use python scripts to select one of the templates in the project and create maps quickly. Since we have only been able to use arcpy.mp to modify existing layouts in the project, we need to use base python to copy the entire project before editing the templates.

What we would like to do is copy a layout template, create a new layout, and then modify that new layout without needing to copy the entire project directory. I can’t find any functionality in arcpy to create new layouts.

Is there a way to make new layouts from python scripts?
