Adding headers (e.g. content-disposition) for static resources?

When using static resources documented here: https://www.http4k.org/guide/modules/core/

routes(
    "/static" bind static(Classpath("/org/http4k/some/package/name")),
    "/hotreload" bind static(Directory("path/to/static/dir/goes/here"))
)

Is it possible to somehow define content-type, content-disposition? I tried to add the header manually, but it doesn’t seem trivial.

Also this might be helpful for adding caching headers for static resources.

We already have a mapping file of extension to content type in mime.types
