Add variables for start time and end time of buckets in heatmaps for use in data URLs

I have a heatmap of Apache access log request durations with buckets for various durations. I now would like to add a data link to each bucket that opens another dashboard which displays the log lines corresponding to that bucket. I tried construction from/to/time/time.window and various other parameters from ${__value.time}, ${__value.time:raw} and ${__interval} but so far I have had no luck getting something that works for the seemingly simple task of calculating a time range to put in the URL that matches the start and end of the bucket. Some of them also seem to randomly be off by 2 minutes, 4 minutes or in one case I observed 12 minutes and it is apparently not possible to do e.g. from=${__value.time:raw}-${__interval} ` https://grafana.<domain redacted>/d/mhfzhb9/apache-access-logs-filtered-by-durations?orgId=1&from=${__value.time:raw}-${__interval_ms}&to=${__value.time:raw}&time.window=${__interval}&timezone=browser&var-virtual_host=${virtual_host}&var-min_duration_microseconds=${__field.labels.duration_bucket_min}&var-max_duration_microseconds=${__field.labels.duration_bucket_max} ` was my last attempt which shows an identical from and to after opening the link (seems to ignore the -${__interval_ms} completely) and is also 2 minutes in the future relative to the time displayed in the popup for the bucket with the link. I am currently using this Loki query (with duration_microseconds being a field in the structured metadata of the line as parsed by Grafana Alloy), I would also really appreciate some sort of built-in replacement for that label_format mess but that at least works fine. ` sum(count_over_time({service_name="apache_access", virtual_host="$virtual_host"} | keep duration_microseconds | label_format duration_bucket_min="{{ if le (int .duration_microseconds) 10 }}10{{ else if le (int .duration_microseconds) 199 }}100{{ else if le (int .duration_microseconds) 1000 }}1000{{ else if le (int .dura…
