Is it possible to specify a function as Dynamic Aggregation Function of a metric and define it as default at the project level, so every new metric comes with this function set as default in Strategy Developer 9.x and 10.x??

Metrics are normally created with the Dynamic Aggregation Function set to Default meaning that the dynamic aggregation function will be chosen based on the metric's formula. As such, the default dynamic aggregation function can be changed at the metric level. For instance, a metric whose formula is simply the Sum of a fact should logically use the Sum function as dynamic aggregation:
