Is there any way to have a visited state or even just a different shape after a button has been clicked on a master slide?

I have spent hours reading the discussions, blogs (especially by Lieve including toggle buttons) and also videos about not being able to change states on the Master Slides. I'm getting the feeling that there is no way to have an indication that someone clicked on a button on the master slide. But just to make sure, since I am a newbie, I wanted to ask again.  I am creating navigation, and I don't care that much about the rollover or down state, but I would like the  user to be able to have a visible indicator they have already clicked on a button. Just like when you click on an Internet link you go back to the page, and the link is a different color. Is there a way to create an advanced action on a master slide where I can toggle to a different shape and jump to a specific slide? That might be a work around for a navigation bar on the Master slide. However, I have not been able to figure this out, and I don't want to keep trying if it's just not possible.  Thanks! Elissa
