Metric Weight and Decimal Places

Is this something that can be added? If you set your weight to imperial you can adjust your weight by 1 pound at a time (.45 kg). With metric chosen you only have the option of an entire kilogram (2.2 pounds). I usually round up to the nearest half, If I weigh 94.2 I’d like to be able to put in 94.5 not 94 or 95
