The NEO 2023 BU was a special case. Since it passed within less than 10,000 km, the perturbations by earth changed the osculating elements so much from day to day, that the MPC's 'NEAs at Today's Epoch' file couldn't keep up with the alterations to the orbit. In one of the threads here from summer 2021 or 2022, BMD & I 'tricked' ST4 to have it plot positions for a single NEO with several different element sets at one time. It was pretty cool to see the object in several positions on the chart. Rather time consuming though & hazardous to your MP DB if you mess up. I recommend making a Backup before trying it.
