How to change URLs for "Page", "group" and "events"

for a "page" a "group" or an "events"

take the example for a "page". example of url:
https://www.cgpigroup.fr/pages/ 29 cgpigroup.html

if I share an element that is in the newsfeed of the page on another social network, the URL is: https://www.cgpigroup.fr/journal/element/14176.html

I do not have the reference of the page to know "29 cgpigroup"

If I want to display a pop up on all the URLs of the publications of this page "29 cgpigroup" it is impossible.

To do this it will be necessary that the URL is on this format:.

https; //http://www.cgpigroup.fr/pages/ 29 cgpigroup.html / journal / element / 14176.html

Is there a solution?
