No, you can work around that. There is an option in config.pro called search_path, where you can define additional path Creo will search for parts, when they're not in working directory. One search_path option can contain only one path, but you can add as many search_paths as needed. Also remember, that Creo doesn't search subdirectories, so you need to set path for every subfolder containing parts.
But, if you have a lot of directories with standard parts, adding many search_paths can be a real pain in the neck, so you can use another option, search_path_file. To use it, first you need to create a simple text file called search.pro and put in it this file all directory paths you want Creo to search for paths (using format one line: one directory path, so it looks like this:
C:\Library\Washers
C:\Library\Nuts
and so on.
Then you put a path to search.pro file in search_path_file option and you can only modify search.pro file whenever you need to add a nwe path.
