joefields suggests a great idea, but my guess is that programming may take a few releases. In the meantime, how about the ability Lining/Insulation thickness to duct & duct fitting simultaneously. Or, if it must remain 2 steps (one for duct, one for fittings) at least allow us to do all the fittings in one step, not individually. Thanks!
