A user has requested "helper" labels on range questions like those below - additional numbers under intermediate ticks (for example, four new labels at the multiples of 20). I have not found a way to label anything other than the start and end values; I see that there are darker ticks at 25, 50, and 75, but that's only a small boost, and as the bottom range shows, they move around when a value is selected!

I would accept any method that achieves this - appearances, parameters, scripting, etc. Any suggestions?
Thank you -
