Assign default aggregate field on Pivot Table - and other enhancements

Thanks for the Pivot Table! I’m finding it very useful. I do have an enhancement request. On the Aggregation Options tab, you can tell the system the default Aggregation to display.

However, on the Properties tab, the field chosen for the aggregation is the first field in the Aggregation group. It would be great if I could set which field to use as the default. It would also be great if I could sort or rearrange the order of the Aggregate fields rather than showing the last added field first. This would make it easier for the user to find candidate fields on the screen when it first loads.
