Shortlist

Hi Fellow RHPers A bit of a technical question - so please forgive us if we are being dummies - but we cannot work out how to add couples we would like to meet into our "Shortlist". We can add to our "Favorites" from their profile page but can't work out how the "Shortlist" works. In the profile stats area we can see that other couples have us in a shortlist, but we don't know how to do this. Any RHP wiz who can tell us please?
