I need to be able to terminate a workflow that Forms started and is currently waiting on to finish.

The particular use case here is this:

Job application is submitted. Stored in the repo. HR selects the job application from the repo and performs an action that send that application to a person in their Forms Inbox for review. The form that is sent allows them to review the application in an iFrame and select them for hire or return them as not selected. I can send that application to multiple people at once. So when I send it to someone I also trigger a workflow that watches that job application entryId for a status change in case someone else hires them first. If someone else hires them the status changes to 'selected for hire' and the user task in forms is interrupted. However, if the hiring manager does not want to hire them the user task is complete, but the parallel workflow that was triggered to watch for them to be hired will wait forever. I need to be able to interrupt/terminate that exact workflow forms triggered just like terminating a user task.
