I agree, the selected transaction sum and avg is a feature that MD should have and should be easy to add. If you don't use Tags for anything, there is an awkward workaround for totals and subtotals by selecting all transactions involved, batch change the Tag to a unique name, then run the transaction report filtering by Tag and subtotaling as needed. Then you run batch Tag change again back to null. Yeah, awkward, but saves some calculator time. But, your absolutely correct, this feature should have been a part of MD many years ago.
