Hello dreamers.
For anyone coming here still looking for this, so was I, and I managed to create something which does exactly what I want.
Here it is:
https://drive.google.com/file/d/1NQyB4u58QWxC8BR-9VgBmy2MEioGuQ2m/view?usp=sharing
It has two triggers.
Either you search for a file the normal way (pressing space), then action it and pick "Paste path into dialog box"
or
You start a custom file search using "p", then just press enter when you've found your file/folder and voila.
Hope this helps someone!
Love
Paul
