Sharing the command line arguments between multiple sln files

I have multiple different folders with the same project (working on different branches of the same codebase), where it would be ideal to share the same list of possible command line options between all these sln files (they have the same startup projects).

Most often I have multiple Visual Studio instances open at the same time so it would be great if making changes in one instance would immediately show up in the other running instances, instead of overwriting each other's changes.

While having the same list of possible command line arguments would be ideal, I'd like to be able to enable/disable them on a per solution basis.

I tried to use the "Use custom JSON Path" option to save the settings to a JSON file, but that file never gets created.

Update: After changing the Path where to save the arguments JSON file to a folder name instead of a file name, it does save it.
But the UI happily accepts a file name without any error message. The actual file name will be the same as the sln file which implies that the arguments list cannot be shared with sln files that have different names, which is our use case (we have separate sln files per platform)
