Engage link

I'm using a ppt. template that has tabs that people can click on to get from one slide to another (e.g., http://community.articulate.com/downloads/p/267178.aspx). I have created an engage pyramid slide where people can click on the layers of the pyramid to obtain additional info. This engage slide doesn't flow with the rest of my presentation because it doesn't have a tab to click on like all the rest of the slides. So the only way to access it is to click on the slide title/number on the outline to the left. Is there a way to refer to this engage slide in one of the main slides with a tab? For example, is there a way I can put "Click Here to learn more about ABC" on one of the main tabbed slides, where "Click Here" is a link to the engage slide?
