I'd like to be able to summarize by activity Name. Or have some other solution to track the mileage on my shoes. Currently I set Activity names based on shoes, but, I found out, that I can't run a report by Activity Name.
I do the same thing, naming the activity, followed by a code for the shoe name. You can then export activities to a CSV and manipulate the shoe data using Excel. If you use a comma or dash, you can then use it as a delimeter to split out the columns by shoe code.
