When making improvements to a library, I usually make a new project and room to place cabinets in that I want to modify.  Then, once mods are completed, I can save back to the library.  When I open Library Designer, this saved cabinet is not in there with the features i added.  The library has to be deleted, and then added in again.  This is a lengthy process.  I want to copy prompts I made in one base cabinet to all the other base cabinets.  My request is that I can update the one cabinet without deleting the whole library and adding it back in again.  I don't really know if it is practicle, but if so, I think it would be a good feature to add.
