Scoreboard Objectives For Damage Resisted By Armour

Currently there are scoreboard objectives for damage taken, damage blocked by absorption and damage blocked by the resistance effect. There is also versions for each of these but when dealing damage. There is also a scoreboard for damage blocked by a shield when attacked. Would it be possible to add 3 new criteria, one for damage blocked by armour when attacked and also when attacking as well as damage blocked by a shield when attacking as the shield information is currently only available for when your attacked.
