S3 Publisher: support different folders for different targets within a single S3 bucket

Please describe your issue:

Is it possible to have electron-forge distribute to different folders within a single s3 bucket? Currently I believe we can push artefacts to a single bucket and directory.

I am hoping to be able to push into architecture segregated structures as follows:

s3://bucket_name/releases/darwin/...files
s3://bucket_name/releases/win/...files
s3://bucket_name/releases/lunix/...files

Is this currently possible? Or planned?

We could make this possible by adding a keyResolver config option. Might look something like so:

s3: {
  keyResolver: (artifactName, platform, arch) => string
}

Would that kind of thing work for your use case?

Thats much cleaner that what I was thinking but yes, perfect.
