I have a blank generic Assemblies built where the formulas and everything are good for metal and wood stud walls, as well as gyp bd. It would be nice to be able to drag and drop the product I want to use from the product list into the item when the properties of the assembly are open. Could make things extremely fast if the assembly is already set up with working formulas for all of the items in the assembly.

I dont use product lists so did not realise you could not do that but you can with items, drag them into takeoffs
I have my item set up but they are generic and waiting on products. So I need to be able to drag the products onto my generic items
