Create new properties for all Activitie - Throw in Current Activity

[Flexa (Guilherme Flexa)]

I would like to suggest creating a new property in all activities.
Property Purpose:
Throw a specific exception in a chosen activity (as in the image).

Benefit:
Facilitates QA testing;
Facilitates throws in flowcharts;
Reduce code;
It allows an identical simulation of what the error would be like if it happened in such an activity.
