Multiple File upload thought form-data

I'm currently using flask_smorest.fields.Upload to handle file uploads, but this only allows selecting a single file. Is it possible to upload many files?

I am trying to upload multiple zip archives serializing request with `flask_smorest.fields.Upload`, in resources im use blueprint arguments with `@blp.arguments(UploadShema, location="files")` and getting file with `f = files["data"]`. But the issue is `f` returns only first file added thought form-data.

How could this issue be resolved?

The issue names flask_smorest.fields.Upload and @blp.arguments(..., location="files"), with files["data"] as the observed entry point. Start by tracing how repeated form-data file parts are parsed there; done means the behavior for multiple ZIP archives is defined and can be verified from that entry point.
