Correct Copybook scanning without extensions

[ChristianKernDev]

In my setup we have the file extension ".txt" on all COBOL files including copies. So i setup the extension in VS-Code the following way:

    "files.associations": {
        "**/*.SRCE.COBOL.*/*.txt": "cobol",
        "**/*.SRCE.COPY.*/*.txt": "cobol",
    },
    "cobol-lsp.cpy-manager.paths-local": [
        "Code/P009.SRCE.COPY.R004"
    ],    
    "cobol-lsp.cpy-manager.copybook-extensions": [
        ".txt"
    ],

The folder "Code/P009.SRCE.COPY.R004" contains all the copies, while all the COBOL code is in "Code/P009.SRCE.COBOL.R004".

But this leads to the behaviour, that i can't navigate to Copybooks from my COBOL files with a ".txt" extension. Probably all my files are detected as copies now.

One example:
File: "Code/P009.SRCE.COBOL.R004/P04T0000.txt"

The Copies are not clickable and the plugin does not even register, that those should be copies.

Once i rename the file, it let's me navigate and even shows, that the copybook contains an error:

Is there a fix or workaround available for this issue, without me needing to rename all files?
