Can I create a Benchmark Group using Google Sheets spreadsheets, custom API integrations, SQL integrations, or third-party integrations?

Currently, benchmarks can only be calculated for native integrations. You can view all available native integrations by navigating to Data Manager > Available Integrations. Set the Show drop-down to Native integrations. 

Spreadsheets, custom API integrations, SQL integrations, third-party integrations, and custom metrics are not currently created in the Benchmarks app.
