Pack and Go vs. SW Explorer

I want to "reverse" a Pack and Go, is this possible? I added a prefix XX to a large assembly with 100+ parts. I now want to make a generic configuration folder of this assembly for future use with different prefix. I understand on an initial pack and go you have the option to add prefix/suffix. Is there a way to pack and go, delete the prefix and start a new assembly folder? Is this something I can do in SW Explorer or do I have to manually select each part to adjust the file name? Hope this is clear. Thanks for any help.
