Allow bulk creation of injects

[savacano28]

Context

When creating a simulation, you have to manually enter and click on each inject instead of adding them in bulk (also adding description, targets..). It would be great if, when selecting the payload or an attack, you didn't have to add additional details with additional clicks.
