Is it possible to calculate the best TimeUnit per logical group?

As far as I understand it, if the `SummaryStyle.TimeUnit` is set to null/default, BDN calculates the best fitting unit, which seems to be the one that can display the smallest value with less than four digits before the decimal point. Usually that's great, but if there is a rather wide range of results for benchmark cases, it can become cumbersome.

For example, when running both a 'regular' (Short/Medium etc.) job and a `[DryJob]` the results are of course very different, but for macro benchmarks, I often need both. Now I can add grouping via `BenchmarkLogicalGroupRule.ByJob`, but while that will affect baselines, it doesn't affect time units.

Is there any way to do that? If not via config/attributes, maybe by customizing some interface?
Thanks in advance for any help.
