I have dynatrace logs that I'd like to compare aggregates for two separate timeframes in a dashboard's table. A working solution I have is to use one `fetch logs` from the dashboard's timeframe, then join with a second log using dashboard variables for start and end time and date:
```fetch logs, timeframe: timeframe(from: concat($PrereleaseStartDate, "T", $PrereleaseStartTime), to: concat($PrereleaseEndDate, "T", $PrereleaseEndTime))```
But this is obviously pretty cumbersome.
Is there a better way to compare logs from two distinct timeframes in a dashboard?
