I know there is an idea for Dynamic Summarize, however I think with only small change to Summarize tool this could be achieved.
If we set the Summarize to Group by all our dimensions but then use ListBox + Action to control which dimensions we want to select - wouldn't it be nice (ahh Beach Boys comes to mind) to be able to tell Summarize tool that if the dimension in group by is not found just ignore it? At the moment it throws an error. I just think such small configuration would achieve this, right?
Please let me know what you think
