Ability to Control the Group by Column Summary Date Formatting

[Brandon Moberg]

Hello! 

With the new hierarchies and connections, the group by functionality is much more powerful now!

One small thing that would be nice is the ability to control more of the formatting when you choose to summarize the column values at the group by level.

One specific example is with dates. Love the ability to show the range of underlying connected solution dates that roll up to the group by opportunity, but the formatting is discrepant and the column summary looks noisy in its current format.

Hopefully, something we can add to the optimization list. Thank you!
