Is it possible to create a new text area field for Create Job Profile page?

Summary:

We have a requirement to store Legal Job Description in Manage Model Profiles for Job page.

Currently we are using Job Description, Job Responsibilities, Job Qualifications field for storing Job Posting description (Job description visible in Career site).

Is it possible to create a new text area which is similar to Job Description. So we can store Legal Job Description in that field.

Is anyone using legal job description in your company. If yes, could you please provide suggestion.
