My company is trying to create better automation of key custom stats for Epics that our various product teams are working on. Two of these are new fields we created called Actual Days (Dev), which we use to track time developers spent coding, and Actual Days (QA), which tracks the same thing but for our QA engineers.
What we want is to create a way to have the values inputted for those fields under child tickets to flow into the Epic as an aggregate sum. For instance, if there were two child tickets under an Epic with the values of 5 days and 3 days for Actual Days (Dev), we'd want to see a value of 8 for the aggregate field (which we can call Actual Days (Dev) Total here).
Is there a plugin that would best fit our needs here to create that aggregate field on the main Epic ticket? Or should we be looking into building a custom report instead. Thanks in advance for your help!
