Workflow - Not required - the button to complete Jobs in Section with in the workflow

Would be good to have a N/A button that fills all items within each section N/A.

A good example would be a Self-assessment workflow. We have each part of the self-assessment divided into sections, Employment, Self-assessment, CGT etc , When you come down to for example section CGT, We need to change each item to N/A, in-progress or done. When you come across a section that is not required, you need to change each part of the section (sale of property, cost of sale, etc) to N/A. One button at the top of that section that changes each item to N/A within that section only. Would be helpful
