New aggregation options for custom metrics

We’ve expanded how custom metrics are calculated and displayed, unlocking more accurate formulas, better time-based metrics, and advanced use cases like weighted averages.

New value types: Seconds & Milliseconds

You can now correctly display duration-based metrics such as average session duration, page load time, or video watch time—without workarounds.

Aggregation method selector

Choose how values are combined, not just summed. New aggregation options include:

Sum, Average, First,

and

Last

This lays the groundwork for broader support across Blends and Source Groups as well.

Aggregation level selector

Control when a formula is applied:

Aggregate level (default):

Aggregate data first, then apply the formula

Row level:

Apply the formula per row, then aggregate the results

This enables more advanced calculations, like weighted averages, that weren’t possible before.
