To do this, you probably want something like umbrella sampling or
steered molecular dynamics. I don't think we have a tutorial for that,
but you can look in sections 6.7 and 6.8 in the manual. When you get
an idea of how to do that, then you can apply the ideas in the
tutorial you cited to use QM. (It should be just a keyword change, and
indicated in the tutorial.)
