Change the "Subject" of a form message section

I am working on a WordPress site, where there is a Job section. Where a user can apply for a job, that is why I have created a `Contact Form` to receive the application with Applicant's Name, email, address & CV's. Now When an applicant clicks to apply for a `Job advert` it takes them to a `Contact Form` Example site - [login to view URL] Application Contact Form - [login to view URL] Now I am trying to get is the Job/Position `Title` as the Subject of `Contact Form`. So right now I am receiving the Applicant name as a Subject, But instead of this, I want to use the `Title` of the Job as a Subject. Which can be found in the `class="info_item"` `<p> Solution Architect</p>` as the form message section. As an example- here the title is `Solution Architect` which means the form subject also should be the same. I have searched almost everywhere and almost everything and I didn't find any solution how I can fetch that Information into the `form message` section! Do anyone knows any solution how I can use that class Info as the Subject of the `form message` section of the `Contact Form`.
