Controlling parent-id being send to downstream services

Hi,

I see this code here.

if (requireParent === true && currentSpan === undefined) { span = trace.wrapSpanContext(INVALID_SPAN_CONTEXT); } else if (requireParent === true && currentSpan?.spanContext().isRemote) { span = currentSpan; } else { span = this.tracer.startSpan(name, options, ctx); }

https://github.com/open-telemetry/opentelemetry-js/blob/main/experimental/packages/opentelemetry-instrumentation-http/src/http.ts#L641-L650

So currently there is no way to send current span as parent-id to downstream services ? I think it would be good idea to re-use current span id to send downstream stream instead of creating a new one.

This will allow for better co-relation between span on server side and client side. I want to use the same same span id as parent-id . Please let me know how this can be made possible.
