How to combine the functionality of source_group and target_sources in CMake?

Question

thanks to this answer regarding source_group and this answer regarding target_sources. I really cleaned up a lot of the way I managed my code base with calling nested CMakeLists.txt files rather than <subdirectory_name>.cmake files. However, I wanted to know if there was a way to further filter source_group(TREE ...)?

As I have it set up right now I have the source_group filters at the root, or parent, CMakeLists.txt file and I have a giant mess of the following:

source_group("subdirectory_name/Header Files" FILES ${libName_subdirectory_name_HEADER_FILES})
source_group("subdirectory_name/Source Files" FILES ${libName_subdirectory_name_SOURCES})

And I have at least 21 subdirectories in this current library. And some of these subdirectories have subdirectories within them. I would like to keep the same pattern if I can since the rest of my project is already set up like this. So it was really nice to know that I could do:

get_target_property(libName_SOURCES libName SOURCES)
source_group(TREE ${CMAKE_CURRENT_SOURCE_DIRECTORY} FILES ${libName_SOURCES})

And it neatly organizes the subdirectories with their sources and header files. However, I would like to further filter that so the headers and files are not combined in the same folder.

Right now, the Visual Studio Project looks like this:

libName
-- subDir1
   -- header.hpp
   -- source.cpp
-- subDir2
   -- header.hpp
   -- header.cpp

What I want to achieve:

libName
-- subDir1
   -- Header Files
      -- header.hpp
   -- Source Files
      -- source.cpp
-- subDir2
   -- Header Files
      -- header.hpp
   -- Source Files
      -- source.cpp

Is there a way to accomplish this with source_group(TREE? or do I have to create a custom source_group in a for loop that will parse everything in a way that I would like it?

Here is a small example of what my project currently looks like:

cmake_minimum_reqiured(VERSION 3.18)

project(myLib)

set_property(GLOBAL PROPERTY USE_FOLDERS ON)

add_library(myLib SHARED)

add_subdirectory(subDir1)
add_subdirectory(subDir2)

get_target_property(myLib_SOURCES myLib SOURCES)

source_group(TREE ${CMAKE_CURRENT_SOURCE_DIR} FILES ${myLib_SOURCES})

set_target_properties(myLib PROPERTIES FOLDER "Lib")

subDir1/2 CMakeLists.txt file:

target_sources(myLib PUBLIC header.hpp source.cpp)

Thanks!
