Payroll Report: Employee Hours Worked by Category

vorocollc

I track the Owner's hours with a $0 hourly payroll, and others at their respective rates. For Worker's Comp and insurance filings, I need to track the hours worked and the categories of work in which they are done. For example, I must track time spent on accounting/office work versus time spent operating heavy equipment or working in a maintenance shop. Is there any chance that a payroll category function could be created for tracking this, and a way to run a report by hours spent by each employee or on each task overall?
Thank you.
