Elders Quorum Service Coordinator calling in LCR

Handbook 2 section 7.3.5.2 describes the callings of Service Coordinator and Assistant Service Coordinator for the Elders Quorum. We’ve recently called a Service Coordinator in our ward and I’m trying to record it in LCR. I can’t find this calling under the Elders Quorum organization. Am I missing it, or do I need to create a custom calling for this? It seems odd to have to create a custom calling for something described in Handbook 2...

I couldn't find a proper solution, so I ended up creating a custom calling "Elders Quorum Service Coordinator" in the Ministering section of the Elders Quorum organization.
