Ability to fix units in result to force set kb and ms in output numbers

Now library tries to automatically pick up best units to display value in pretty way. It looks good, but sometimes it is not useful, because we can't quickly reveal high numbers in list of numbers with different units.
For example, in Time column there are numbers:

298.98 μs
123.53 μs
 46.02 ms
 41.43 μs
 42.24 μs
194.53 μs

Can you quickly catch most longest operation via quick look? Not so easy! But if we fix units to ms, we can easily catch this problem, here is example:

 0.29 ms
 0.12 ms
46.02 ms
 0.04 ms
 0.04 ms
 0.19 ms

Same problem is with memory usage too.
So will be good to add an option to fix measure units to needed values, or maybe auto-detect them between whole list of data, not for each value separately. What do you think about this idea?

Also sometimes we need to see exact values, for example exact increase of memory usage in bytes instead of 0.00 KB, so via this feature we can force set units to bytes to see exact values.
