Yes, although perhaps not as neatly as you would wish.
This should get you started:
MACRO: Choose File From Folder List With Incremental-Search and AutoComplete
At present:
- It only supports files – not folders.
- It does NOT function recursively.
- I does NOT support multiple folders.
- It opens the selected files.
- The folder-lister is AppleScript but can be changed to km-native actions.
All of these issues can be overcome.
