Premise:
When creating symbols, using the [Manufacturer] and [Model Number] are really useful especially when Creating a new UDP from an existing UDP. So many variations of products e.g. signal extenders, video switchers and scalers with slight IO changes benefit from not having to manually edit every field for all symbols in a UDP.  

Can we not also have the [Description] attribute? Moreover, could this attribute be set as default for a new diagram symbol?
