Currently it is not possible to create a cube refresh subscription in Command Manager. However, users can achieve this functionality by creating a cache update subscription to refresh Intelligent Cubes. Both types of subscriptions when targeting intelligent cubes will submit the same SQL statements to the database.
The following on how to achieve this is done in Strategy Tutorial 9.4.1:

CREATE CACHEUPDATESUBSCRIPTION "cube cache update" SCHEDULE "all the time" USER "administrator" CONTENT "Intelligent Cube - Dynamic Sourcing" IN FOLDER "\Public Objects\Reports\Strategy Platform Capabilities\Strategy OLAP Services\Intelligent Cubes and View Reports" IN PROJECT "Strategy tutorial";
