It would be a real asset to be able to add Part types. Or at least have types for all fittings such as Combos, San Tees, P traps etc. It is too much to scroll through to find the right fitting when everything is under Tee. Along with this, there would have to be a way to add the combo, san tee etc type to the auto connect dialog since at this point it only recognizes a type labeled tee.
