Dynamic Triggers in that pack might help. It basically transforms UIText atoms in variable holders, and they can replace anything in any trigger. You add that plugin to an UIText and set a trigger in it that sets the speech bubble to "Example!", and in the plugin set "Example!" as the string to replace. Then, whenever you trigger the plugin, it will do that trigger that you set (to update the speech bubble) but it will also replace "Example!" with whatever is in the UIText atom text. So it will update the speech bubble with whatever you have in the text atom.
