trap item for mobs, dropping their loot

Hello, sorry if there is already a thread, I couldn't find it. I want to make an item that absorbs a mob and then drops its loot into the inventory of a special block. It is not necessary to register loot from mobs in each item separately, because some mods change their loot and you need to register loot from mobs, and not individual items from them. I hope you understand and thanks for the help.
