Hi
Solution for Windows only:
My scite customization script includes a function loading a user strip loaded with the first 1000 results from "dir /s/b *.*" for the directory of the current file.
This function calls several others - but they are all contained in the single script file.
My keybinding is CTRL+ALT+O - but you could edit this within the script.
Kind Regards Gavin Holt
