Add approvers directly to timesheets, even if they've already been submitted for approval.
Open the timesheet you'd like to add an approver to. Then open the drop down menu and select "Add approver". Select the approver you'd like to add from the list of approvers available on the contract.
Finally choose "Add approver" to save the approver. An email will be automatically sent to them requesting their approval.
You'll need to add the approver to the contract first, see the Adding a contract approver guide to learn how.
