Want to add custom coloumn in Redwood Time card page in day wise

Summary: we have custom option to approve overtime hours on a daily basis to the manager in classic Time card page,when we migrate to Redwood Timecard,we are not able to provide this option.If i add this in additional attributes the Existing layout of Timecard shows all the days in a single row,how can we add this option on daywise.

Please refer the screenshot for layout sets if i can able to add a coloumn in Day along with Start,Stop,quantity i might add my Time attribute of overtime by providing the options YES/No,Manager can choose and approve.
