Add b3 trace header as tag

I currently have setup zipkin tracing so all my requests in Django will have the headers:

Is there any way to have these alongside my django trace tags?
My setup is currently just:

    # If you wish to associate users to errors (assuming you are using
    # django.contrib.auth) you may enable sending PII data.

Thank you

You can add custom tags using the example provided here:

So you could write a Django middleware that takes the header and copies it into a tag.
