Is there a way to add bulk of files to a Visual Studio C++ project?

Question

I need to add many source files to a new Visual Studio C++ project.
Probably around 3k+ files, distributed between several nested folders.
I am using Visual Studio 2022.

I tried to drag and drop the files but:

1. It takes forever,
2. I need to do this per each nested folder

Is there a way to add these files, or base folder, which will add all nested files/folders recursively?
