Work in Process , Rescheduling midpoint Forward

We are on 11.5.10 . I want to mimic the functionality behind the reschedule button on the Job/schedule details button, via an api /interface.

I read articles regarding that  this can be

A)Manually accomplished by providing start and end time for the operation resources from the current operation.

B)Automatically rescheduled by providing print explosion=Y and providing the schedule  method.  However it reads the primary routing and does it for the entire job.

Is there no way to reschedule from the current operation forward via api/interface (just like the job schedule detail screen does) , so that oracle automatically calculates the scheduled start and end times for the rest of the operations?
