Importing a New Product Forecast

Summary

Measures & Process when NPI forecast is done outside Demand Management

Say a customer does not use Manage Product Launch (IoT Planning Advisor), but just prepares a forecast for new products offline.

So we need to import (using fbdi template) their forecast into a custom measure.

What is the best way to automatically populate Adjusted Shipments Forecast with the imported forecast for any new products?  Can/should this be done by tailoring the measure definition of Adjusted Shipments Forecast - ie if 'new product' then Adj Ship Fore = imported measure?  is there another/better way?   what is best practice for this use-case?
