Firstly, thanks for taking enough of an interest in your FO's development to come here and ask.
Might I suggest though, that instead of providing him/her with a crutch to use, you allow the person to do it visually. It can be challenging, as sims aren't really good at visual manoeuvrers, but I think in the long term, your FO will look back and thank Captain JT8D for teaching him how to do a visual approach. It's ok to mess it up a few times, too. We debrief and have another go next sector.
