I want to use "dialoguema_dialoguemarkart_0006477f_1" for a new NPC, but I can't change the voice filename or path. Should I make a copy of the voice file I already have, rename it and put it at the path?

I just rename the file (the pre-existing file) to what the CK says for the dialog and make sure the path is right.

Okay, when I save the mod, these files will all be included in the esp?
