Timesheet - Plugin Rules to be reviewed and rules added to Work Patterns

We have a mixture of Hourly Paid Staff and Salaried Staff and We were looking at implementing the timesheet plug in option within people HR and the excel file option, However we hit snags with this in relation to rules etc. Overtime couldnt be approved on a person by person basis on the planner with the need for a logbook which didnt work as expected. An Idea is to incorporate the Plugin options into the planner and approve exception similar to how Core XD would see this, approve this and calculate hours
