When you use a Preconfigured Section in the new C360 layout, and add that section to various layout(s), then change the name of the Preconfigured Section, the name change is not cascaded to the section in each layout where it is used and instead retains the old name of the Preconfigured Section. This means you need to go into each layout where the section is used and update the name individually.

I would like to see a name change of a preconfigured section cascade to the layouts where the section is used.
