How can I submit the same GUID multiple times in a Visual Studio Code REST Client request

Question

When I need to use the same GUID in several instances - e.g. HTTP Header and Body - how can I achieve this?

Correlation-Id: {{$guid}}

{
  "CorrelationId": "{{$guid}}",
  "Record": [

Correlation-Id: {{corrid}}

{
  "CorrelationId": "{{corrid}}",
  "Record": [
