how to setup a job set for several ESS job to create index........

Summary:

Prior to Redwood, we had to run "ESS job to create index definition and perform initial ingest to OSCS" once, with just the one parameter after every P2T or quarterly update. Since Redwood, we now have to run the job 19 times for 19 different parameters!

I'm thinking of setting up a Job Set on production that is never run on that environment but is run on a test system after a P2T. I can enter the job set name, description etc. However, when I come to create the steps, I cannot find "ESS job to create index definition and perform initial ingest to OSCS" via the search function. What am I doing wrong? What should I search for to fin that process?
