Deleting a dialogue

[JuurikasvonJobu]

So, I've duplicated a character in Skyrim, and was wondering if there is a way to delete the whole dialogue options attached to this character, while the original stays intact?

 

Also, I couldn't figure out where to find that specific character dialogue, as there seems to be all the dialogues in the game together, which means there a literally tons of dialogues in one place. Kinda seems like finding a needle in a haystack.

 

Don't like to ask so stupid questions, but I'm kinda tired of getting crashes from the Creator Kit.

Thanks in advance! :)
