Possible limited "Search marco" scope?

I am using Alfred when searching for macro. I seems to remember there is one build-in search like spotlight but I can’t find it in google any more. (Not from the editor)

My question is, is it possible to limited the search scope to only certain folder without doing it in the editor?

The fallowing is the code to trigger in Alfred,

-- No error checking to make sure they actually have KM
-- The passed query is the UID of the macro
tell application "Keyboard Maestro Engine"
  do script "{query}"
end tell

I am wonder if there is any option to let me do so. Thanks again!!
