Would it be possible to add some additional options to the running total, in particular average (max, st dev. may be useful) to the running sum tool or create a rolling average tool where you can group by multiple fields and have a rolling window for the last x rows, which you select? I know this can be done in the Multi-Row formula and with the moving summarise tool tool (http://www.chaosreignswithin.com/2014/12/moving-summarize.html), however the former is capped by 10,000 rows and alteryx crashes on my mac when trying to click on the multi-row formul tool with 6000 rows. Also it takes a several hours to analyse 1 file, and would like to have a solution to do this on a daily basis. Also I need to be able to so a rolling average over the last 11,999 rows, as this would be the last 20 minutes of data using a 10Hz GPS unit. This would be a great tool I think.
