[option to] Auto expand column names by inserting spaces

e.g. UserCountPercentile99 -> User Count Percentile 99 In Cosmos / SQL / etc are columns are things like 'UserCountPercentile99'. The title line in graphs with multiple of test look poor. (We can rename columns via Excel, but we don't always want Excel and we don't always want the extra work)
