Hi there! If you haven’t already, we’d recommend reviewing this support page on response weighting and this support page on custom metrics to help you get started. If you still have questions after reviewing the linked support pages, you'll want to reach out to the Support team, as they are best equipped to help answer questions and provide support!

We are also encountering this issue. We have a dashboard where we'd like to combine multiple data sources that each need a different weighting scheme. The platform gives us an error and does not let us add all of the variables we need. We reached out to support and were told that there is not currently a way to weight different data sources with different schemes in dashboards.
