Select multiple dates in Android DatePickerDialog

I've got a requirement to select multiple dates from Android DatePickerDialog. Below is my snippet. With this, I'm able to select only one date. I've seen other libraries like https://github.com/square/android-times-square. But, I'm more interested in native Android code.

override fun onCreateDialog(savedInstanceState: Bundle?): Dialog {
        val currentDate = Calendar.getInstance()
        val year = currentDate.get(Calendar.YEAR)
        val month = currentDate.get(Calendar.MONTH)
        val day = currentDate.get(Calendar.DAY_OF_MONTH)

        val maxDate = Calendar.getInstance()
        maxDate.add(Calendar.MONTH, 3)

        val datePickerDialog = DatePickerDialog(activity, onDateSet, year, month, day)
        datePickerDialog.datePicker.minDate = currentDate.timeInMillis
        datePickerDialog.datePicker.maxDate = maxDate.timeInMillis

        return datePickerDialog
}
