Forecast Tree

Hi, experts For example, the product hierarchy includes 3 levels, item, and 2 levels above item are product family and color attribute, the are no relationship between product family and color. The question is, can engine generate forecast at product family * color level?

so, in table below, I want to generate forecast at A*W, A*B, B*W and B*B level, so the history quantity shall be 400, 200, 1200, 1000 for each combination. Is it possible to let engine run this way in current hierarchy level, we don't want to have another level like product family*color in Demantra? if engine can support, how to set up the forecast tree, thanks
