Question slides following a text master, question text going into the title text

The question master layouts are counterintuitive, in that the "Question Title" is the question statement. More to the point, it also shows up in the menu as the title of the slide. This is unlike the content master layouts with a "Slide Title" that shows up in the menu.

Is there anyway to have an actual question title (which shows up in the menu) that is separate from the question statement?

I am aware the slide titles can be manually changed in the menu. But also aware that this takes a lot of time in a longer quiz or WTB.

Also, I am not able to make Joe Vinson's solution work. When his entry states "text box that is the highest layer," does that mean on an actual layer, or just moved higher in the stack on the timeline? Either way, it does not seem to work for me.
