[UE5 Project Solution] Hide AdditionalPluginDirectories from Solution View

Since UE5 (I think it was 5.3) Unreal projects can have Additional Plugin Folders linked to the project by putting this into the build.cs file:
```c#
"AdditionalPluginDirectories": [
        "../../Foldername"
    ]
```
Or via The Plugin manager (top left is Add Plugin Folder Button) ...
... to f.e. link a folder outside the project…  Or even link the whole Launcher Marketplace Plugins Folder to a Source-Engine project, to not always need to copy & paste plugins over from launcher to source Engine to update.

Now, this new feature leads to a massive problem with the Solution Explorer.
Not only the Project itself is listed under Games - for me, there are now 250 Folders and I need to play "Where's Waldo" with my project Folder to find it…

Is there a way to HIDE the additional Folders from the Solution View?
