Generating custom operationName for Traefik jaeger tracing

on configuring tracing for jaeger, it is generating operation names based on frontend backend combination, which is not helping in creating a proper sampling configuration. In jaeger, we can create sampling configuration per servicename-operationname combination, but since the operationname is same for all requests which have a given ingress rule configured, we are unable to form a per operation sampling rule.

Is there any way to use URL as operation name instead of frontend-backend rule? If there is some workaround, please let me know.
