Examples:

1.required to add photos before changing status to done pending approval

2.Can we send a customer review request, was he happy:Yes/No (tech will fill)

3.Callbacks: Create a callback form using custom fields for callbacks job- require photos, customer signature, Description of what was done.

if there was a way to make custom fields required before status changes we could have saved a lot of time, mistakes,back and forth with technicians and customers
