PSF File Redirection Fixup Confusion

Hi.

I've been trying my hand at this problem for a few days now, but I feel like I've just been working myself in a circle, so I'm here now to ask this to some people who actually know what they're doing. Anyway, my problem is this:

I have an program that writes to the user's Documents folder. I'm using the KnownFolder section along with the Documents Folder GUID to try and redirect the program's writes to the Local AppData folder, but nothing I've tried has been able to stop the program's folder from appearing in regular Documents.

I've included below the KnownFolder snippet straight from my config.json file.

"knownFolders": [
    {
        "id": "{F42EE2D3-909F-4907-8871-4C22FC0BF756}",
        "relativePaths": [
            {
                "base": "",
                "patterns": [
                    ".*"
                ]
            }
        ]
    }
]

I guess my absolute question is whether or not this Fixup even has the capability to do this. Have I just misinterpreted what the File Redirection Fixup is for?

I hope my question has been clear enough, and I hope I can finally get a solution to my little conundrum here.

Thanks.
