Leave bottle & pump parts in uv sterilizer

Hi mummies that uses uv steriliser. Once after youve sterilised baby bottles and/or pump parts, do you leave it in the steriliser once dried & sterilised ? If yes, what if we have another bottle or pump to dry and sterilise. Do you take out the one you stored in steriliser put it somewhere else while you run the dryer & steriliser of another bottle? #FTM
