Selecting several objects in the outliner

Hi!

I have an annoying workflow problem:

I have hundreds of objects that have the text “emitter” in their name.

I’m able to get them all to show up in the outliner by using the search box (and typing in “emitter”)

But I can’t find a way to quickly select them all from the outliner. Instead I’m shift+leftclicking each line separately to get them selected. While thinking “surely there must be a better way”.

So is there some way to select all the objects in the outliner more quickly?

Okay so basically the answer is: “You’re out of luck”?

But is it possible to literally unpack a .blend file?
So we have subfolders like in file/append view? And then “repack” back to .blend file.
It this is possible, then it would be easy to sort out things with some file manager.
