Endermite triggering endermen NBT tag

As of right now, endermites that spawn from ender pearls trigger endermen into attacking them. However, ones that spawn from spawn eggs or summon command do not. I suggest a small boolean NBT parameter specifically for endermites that map makers can choose if they want the endermite to trigger endermen or not. Something like this:

/summon endermite ~ ~ ~ {TriggerEndermen:<true|false>}
