We would just send our realtors listings we wanted to see and they would screen through them for whether they're overpriced, if they had any red flags for location, and then set up all the visits for us. They scheduled them outside of the open house times so we had the visits all to ourselves. They would also add in ones they knew about once they got the sense of what we were looking for. The one we ended up buying was one they picked because we thought it would be too expensive (ended up getting it for close-ish to asking).
