Make generated client take an io.Reader for parameters of type file

Problem statement

I want to use a generated client to call a route defined like this:

  - in: "formData"
    name: "body"
    required: true
    type: "file"

This results in a type with a member like this:

/*Body*/
Body os.File

However, the data I want to send is in memory, not in a file. Can this be made an io.Reader instead?

Please remove the sections that don't apply

  - in: "formData"
    name: "body"
    required: true
    type: "file"
