Ion-picker selected value

Anyone know how to pass which values to select to an ion-picker so it behaves the same as ion-datetime?

Currently it resets each time and the currently selected value is lost.

Off the top of my head, I would say the date as an ISO string. Haven’t used that particular control, though.

 columns: [
        {

          selectedIndex: selectedHoursIndex,
          options: [
            { text: '01', value: '01' },
            { text: '02', value: '02' },
