Sales Forecasting and Assembly Orders


In NAV 2013 R2 is it possible to use Sales Forecasting (in Production Forecasts) with Assembly Orders or is this limited to Manufacturing Production Orders?

I am currently working with a situation where Assembly Items are created using Assembly Orders that are generated at the point of the Sales Order being raised and posted on the Shipping of the goods.

Or is this possible in Sales Budgeting?

Many thanks in advance
