FM or BAPI For task creation in quality notification

Is there a FM or BAPI that can be used to create a task in for an existing quality notification.

I have tried BAPI_QUALNOT_MODIFY_DATA but it can only modify an existing task in a quality notification.

I have also tried BAPI_QUALNOT_CREATE but it can only create a new quality notification and not create a task in an already existing quality notification.

Please kindly provide with a solution.
