How to Avoid redundant label editing?

Hi! Our company projects will consist of  the  software simulations of “Show Me”, “Try It” and “Test Me” modes. In other words,  Demo, Assessment and Training.  When I’ve created tests, the labels that are created don’t appear to be linked.  So, if I change a label’s, background, font, and text, I have to change all of the versions one at a time.  Is there a way to link these, so I don’t have to do this?  Thanks!
