Anyway to have component requirements show earlier than start date of parent wip job?

In ASCP options we have the Material Scheduling Method set to Operation Start Date. Our internal supply chain performance historically is at around 75% on time. Because of this we struggle from time to time with material shortages at the beginning of jobs. We are wondering if there is anyway to have planning "see" that requirement x-days prior to the start date of the parent wip job? Any and all suggestions are welcome and thanks in advance!
