The answer is "no."
One way around that is scripting. But Encore doesn't do scripting.
The way to do this in Encore, to use "autoactivate" on a button in your menu, and to go to a different menu that has the text for that button. You create multiple menus, one for each text option. The user sees it as one menu.
Be aware that mouseover won't autoactivate, so this option doesn't work on a computer the way you'd like.
