Creating a link so it opens to a certain section of my website

I want to create a link that opens a page on my site. But not only open to that page but select a particular tab.
See what I mean here: http://www.pcigeomatics.com/support/training-services

There are 4 tabs on this page, I want the link to go to this page and have the third tab (‘Training Agenda’) open. Is this possible?

thank in advance
