> Learn how to edit the masterformat section of products from Acelab's database and placeholders added to Schedules.

*Written by Armaan Shah · Updated February 10, 2026*

You can manually change the masterformat section of products added to schedules. You can also add masterformat sections to products that don't yet have one automatically assigned. The change remains until manually modified again.
