The project´s stakeholders needs to visualize the average delivery time of a product.

The estimated delivery date of the product is in data source A and the actual delivery date is in data source B. So, we created a dashboard with the two data sources so that we could cross the two pieces of information.

These two data are of type date. And what we were trying to create, is the average delivery time view between them. But, apparently, there is no way to do this "calculation" within the platform, to display this information on a dashboard.

Has anyone been through this situation (or something similar) or have any idea how to get around this point?
