I talked to support and the Tabs shortcode doesn't support this.  You have to use javascript or buy their Live Tabs module.  Fortunately, there are scripts online that can parse url parameters.  

Heres the one I used: https://www.sitepoint.com/get-url-parameters-with-javascript/.  

So instead, your url should look something like this: http://website.com/webpage?anchorlink=link1. 

What I did was make a script that checks to see if the anchorlink parameter is set.  If it is, activate the click event for that link.  This highlights the link and also makes the tab visible.  You can make the url parameter anything you want.
