Yes you can do this, it's very easy!
It's fully controllable by behaviors - If you want to navigate to a specific tab or start an event within it - it can be easily done with the Control DMXzone Tabs behavior.How to go to the 'previous' tab:
1. Place the link (text/button/image) at the bottom of the tab
2. Click on it
3. Select: Tab Inspector > Behaviors > + > DMXzone > Control DMXzone Tabs
4. Select: Go To Prev Tab
That's it! When you click that link it will jump to the previous tab.
You can also go to a specific tag, the next tag, enable/disable tag, or start/stop rotation.
