Conditional Ticket Fields (Back-End)

Following the advice here: https://wordpress.org/support/topic/conditional-ticket-fields/ I have created the fields for the front-end. However, now I have a huge long list of fields in the Back-End view, and the Save attributes is all the way at the bottom, which is a hassle.
How can I apply the same conditional logic to the back-end so that only the relevant fields appear for the Agent?
