Multiple Summary Numbers
I've been working with this solution to beefing up my summary #s for about two years: https://dojo.domo.com/t5/Beast-Mode-ETL-Dataflow/How-to-Create-Multiple-Summary-Numbers/m-p/2722/highlight/true#M134
It is, however, a workaround. You have to really work with the beast mode to do a lot of rounding and inserting text strings to get the summary number to display neatly. And once your metric goes from three places to four, ex 999 to 1,000, the whole thing displays wrong.
I would really like to simply choose two metrics to summarize in the menu within card builder. It would be great to chose a separator (ex new line, |, /, ",") and display two numbers with that separator in between, like this:
$1,000 Total Revenue | $100 Average Price
