How to set boundaries per histogram?

[vgarvardt]

Setting default buckets/boundaries for histogram is relatively simple:

func InitMetrics(serviceName string) (http.Handler, func(context.Context), error) {
	config := prometheus.Config{
		DefaultHistogramBoundaries: []float64{0.0, 50.0, 100.0, 200.0, 400.0, 600.0, 800.0, 1000.0, 2000.0, 4000.0, 6000.0, 10000.0, 15000.0, 20000.0, 30000.0, 450000.0, 60000.0},
	}

	ctrl := controller.New(
		processor.NewFactory(
			selector.NewWithHistogramDistribution(
				histogram.WithExplicitBoundaries(config.DefaultHistogramBoundaries),
			),
			aggregation.CumulativeTemporalitySelector(),
			processor.WithMemory(true),
		),
		controller.WithResource(resource.NewSchemaless(
			semconv.ServiceNameKey.String(serviceName),
		)),
		controller.WithCollectPeriod(5*time.Second),
	)

	exporter, err := prometheus.New(config, ctrl)
	if err != nil {
		return nil, nil, fmt.Errorf("could not instantiate prometheus exporter: %w", err)
	}
	global.SetMeterProvider(exporter.MeterProvider())

	return exporter, func(ctx context.Context) {
		if err := exporter.Controller().Stop(ctx); err != nil {
			log.Error(fmt.Errorf("could not properly stop prometheus controller: %w", err))
		}
	}, nil
}

But now I want to add one more Histogram metric to my app and it should use completely different set of buckets. How to set custom boundaries for the metric?
