I google the file name and it always takes me to the pack. Better than manually opening each addon, if I've understood you correctly.
Say a save I have uses "Brick_LLDoors.zip"
(a pack of doors), and Im missing "PeepHoleDoorClosed.blb"
(one of those doors), the addon reader will only tell me I'm missing PeepHoleDoorClosed.blb.
And googling "PeepHoleDoorClosed.blb" doesn't refference Brick_LLDoors.zip in any way either so I'm not sure what you meant there.

So Id be left with opening all brick addons I might have or using the file search to find where PeepHoleDoorClosed.blb is.
It's not a fast process. However, Im not even sure if an addon could feed me the zip file names the addons originate. But it'd be nice if it did.
