Adding Custom Entity to Queue using a workflow

Hi All

I have Dynamics CRM 2016 On-Premise and have a workflow that processes a custom entity based on certain field changes.

I want to have this workflow add the custom entity item its processing to a Queue, but cant seem to see how to do this OOTB.  Is this something I need to create a custom workflow to do?

I can select an Action to ADDTOQUEUE and can set the DestinationQueueID but cannot find a way to set the Target.

I have enabled Queues for the entity.

Thanks
Wayne
