Is it possible to append the share by each user with UTM or web address parameters? The use case to have a reference code in the link to know which user may have brought someone to the site (and further personalize the site using tools like unless.com, etc based on the link parameters).

If the answer is yes, is this something that I can manage as the admin or does each user have to go in and setup their query string parameters or UTM fields? And I'm assuming it would be set globally for all shared posts, not something they have to edit a post and update prior to sharing?
