how to achieve two kinds of forecast in one demantra instance

Hi, Expert

Following is our case in one Demantra implementation, any idea is appreciated, thanks a lot

because of data problem, we need to do 2 kinds of forecast in one demantra instance, for example, the input (quantity_form)  are A and B. A and B are for dirrerent combination, no overlap. so is it possible to achieve this by setting up 2 engine profile(Base and Batch). if so, should we load actual_quantity for Both A and B, say merge A and B before ep_load_main run, or we can load A in actual_quantity and B in another column, then use quantity_form in Base and Batch to achieve this? anyone encountered the similiar case before? any idea is high
