Attach candidate facing documents for a job after posting it on Career site

Is there an ability to attach candidate facing documents for a job after posting it on Career site?

We are looking for this feature where a candidate-facing attachment can be added to a job requisition along with Job description on a career site. Once the Job requisition is posted can this action be done?

Use case:

We have few job openings which were posted in the past we need more candidate facing attachments on the jobs posted.

How can we achieve this.
