Trial Shift Process

We potentially have some trial shifts coming up, and I was wondering if you could advise me on the best way to manage these in Fourth.
Specifically, how should we set up individuals in Fourth for a paid trial shift? If a trial shift doesn't lead to employment, what is the process for adding them to Fourth so they can be paid for the shift without completing the full onboarding process?
I'd appreciate any guidance you can provide.

Thank you
