alternate double click for slash as delimiter

Question

I'm using Bash in gnome-terminal in Ubuntu 16.04. Sometimes I want to double click and select one level of directory in a path, using slash as delimiter. I'd like to keep the default double click behaviour (e.g. select "/the/whole/path"), but for example Shift + double click would select one level of directory (e.g. "whole"). Is there such a plugin or script that implements this?
