create a rolling roster

kodey I have to admit, I hadn't heard that expression before today, but a quick Google search found this blog post: https://easyroster.net/blog/what-is-a-rolling-roster-how-will-it-benefit-your-business/ 

The blog post also contains two free Excel templates: an Employee Timesheet template, as well as an Employee Scheduling template, which might be a good place to start.
