Is it possible to trigger a custom ESS job to run from the Payment Process job?

Content (please ensure you mask any confidential information):

We have a custom ESS job that runs a BIP Report and outputs file to FTP location. This custom ESS job is currently run manually by a user after the seeded Payment Processing Request steps are all completed. Is there a way to automatically trigger the custom ESS job to run after the payment processes are all run?

The Payment Process Requests are run by the users at different times, so there is no set schedule we can leverage on scheduling the ESS job on it's own.
