Dashboard shows the sum of measurement values of Gauge

I have a service in which an ObservableGauge\ instrument monitors approximately 90 components and has an `observeValues` callback that returns the latest processing duration of each, as IEnumerable\\>. Each measurement also has a tag whose value is the name of the component. When I make the service export these to the Aspire dashboard over OTLP and don't set any filters in the dashboard, both the "Graph" and "Table" options in the dashboard apparently show _sums_ of the durations. It would be better to show the maximum or the average, rather than the sum. According to [OpenTelemetry Supplementary Guidelines for Metrics](https://opentelemetry.io/docs/specs/otel/metrics/supplementary-guidelines/#additive-property), Asynchronous Gauge values are not additive.
