Larry,
You can do this but it relies on using DxDataBook with a parametric database to push the correct PKG_TYPE property onto the symbol in the schematic, you can't do this just in the tools. Though by the sounds of it you already have some kind of parametric database to handle the different values of the generic device families such as CAP0402 etc. This would just be an extension of that.
