Hi,
I just want to add that I found out just awhile ago that since 2019.1 update in Revit, they now support Sectional Perspective Cuts.
2- EASIER WAY TO CREATE A SECTION-PERSPECTIVE
Autodesk made many changes to the perspective settings to make them easier to use. The most helpful change is the automatic creation of a matching section box when you orient a perspective to a section. In the image below, we want to create a section-perspective matching the section. First, go to plan view to create a section.

Then, enter any perspective view. Right-click the view cube and select the option Orient to View - Sections. Pick the correct section.

Here is the new part from Revit 2019.1: the view will not only be aligned to the section, but a section box will also be created to match the section cut plane and extents. This makes the process of creating a section-perspective much easier.
My comments:
But ofcourse we still have to align the Sectional-Perspective to a Section to make sure both are to-scale, since Perspectives are naturally Not-To-Scale. But it is still a much simpler step than to overlap them like previously. 🙂
