Conversion Pixels

I have a client working with a marketing group that wants to add conversion pixels to a specific job page and an element of another application page.

1. Add conversion pixel before the </body> tag on this page: https://ocrc.net/current-studies/n-22-2/
2. Add a different conversion pixel to the submit button on this page: https://ocrc.net/current-studies/apply/5555/

Has anyone found a way to do this, via free or paid versions of Job Manager? If it’s not possible, has anyone found a better way to manage redirects inside the plugin so we can create a specific thank you page just for this job? Thanks in advance!
