Currently, to my knowledge, HubSpot only allows the weighted amount to be calculated based on the pipeline stage probability.
In our case, we calculate a custom weighted amount using a custom property: Confidence % × Amount
It would be extremely helpful if HubSpot allowed us to define our own formula for the default weighted amount. This way, the custom calculation could be used consistently across the platform (e.g., deal pipelines, reports, and dashboards) without relying on a separate custom property.
