"Share" button upgrade request

[LMGildersleeve]

It would be very helpful for those who are using the "Share" button from Z to be able to add a tc code before posting to a social media account or email.

For example as it works now, when we use the "share" button from a product page the link is shared without any way to add a tc code. If we could track our traffic of sales to the source (Pinterest, blog, website etc) that would help us to determine where the sale came from.
