My solution by the script is attached. 13987-simulaion-trial.fsm

The key is using the label of 'press' and the initial value is 0.

0 means not using 'press' processor and after press processor it is changed to 1 value after OnProcessFinish trigger.

According to the 'press' label value, each processing time in the multiprocessor is changed 'by case' script.

If a question, let me know it without hesitation.
