On the project status, default 'Include attachments in the workflow' as checked

Summary:

We have enabled the project status workflow and validated that when the 'Include attachments in the workflow' is checked, the project-level attachments are included in the workflow. Is there a way to default the 'Include attachments in the workflow'? Can a sandbox be created to update the field has checked? If so, what settings need to be made on the sandbox?
