Is there a way to disable mob drops?

[ddess]

I'm trying to make mobs (zombies) not able to drop any of their vanilla items, like rotten flesh and armor/tools items. Is there a way to do that other than clearing them every tick?

When you spawn the mob, place this block:

and open it's chest and click on the bottom right to disable drops.
You might need to select the block's target tho, to do that, shift-right click the action's sign and click on Last Spawned Entity.
