Ability to hide subtasks from Process URL

Would like the ability to create subtasks for processes, but not have them visible on the shareable links. Internal IT uses the processes for tracking onboarding/offboarding for users and share the link for these processes with HR/Recruiting. We would like them to be able to see the high level Tasks only as the subtasks are steps to check off for internal IT dept and clutter the view that HR/Recruiting sees and has to sift through to find statuses of the process that they care about. We don't want to make the subtasks optional as that would make it easy for desktop support to miss a step and still proceed to completing the process when it is not 100% done.
