Hi Jose,
Since you have many highly customizable capabilities with Empower, you need to add the tab manually. This allows you to create very specific interactivity exactly how you want it. I suggest you contact support to have them walk you through it - that way, you can ask questions along the way and get the exact answer you need. The phone number is 866-852-6700. If you would rather email, you can submit here: http://rapid-e-learning.trivantis.com/Contact-SNAP-by-Lectora-Support. Please let me know if you have any other questions!
