With Wave 4 comes a card called "Sensor Jammer" as seen here:

"When defending, you may change one of the attacker's hit results to a focus result. The attacker cannot reroll the die with the changed result."
Now, how does this happen and in what order?
For example, the attacker rolls attack dice and comes up with hit, focus, and blank. Does the defender have to declare first that the hit will become a focus? If so, and the attacker has a focus action, the attacker may just change it back to an attack. Or does the attacker have to declare first if he is using his focus and then the defender changes the result back to just a focus?
