Can you limit editing of certain worklog attributes to users with approve timesheet permissions

[Örvar Guttormsson]

Is there any way to limit specific worklog attributes to Tempo Approver permissions.

For example,
Our Tempo approvers want to approve each worklog individually rather than entire weekly timesheets at once by using a checkbox attribute that the entered worklog is indeed approved.

With the current setup the users themselves can edit this attribute and check the worklog as approved.
