+### Multiple launches

+To show statistics for multiple launches on a single entity, list them as comma-separated values:
+
+```yaml
+metadata:
+  annotations:
+    reportportal.io/project-name: my-project
+    reportportal.io/launch-name: Unit Tests, Integration Tests, Contract Tests
+```
+
+Each launch will be displayed in its own expandable accordion section within the overview card.
