Phonetic names in contacts

My family has a last name that Siri never pronounces correctly. I also have a lot of contacts with that last name. Is there a way to change the pronunciation for all of these names at the same time without having to make an phonetic entry for every contact? Thank you!

You can also tell Siri she is pronouncing wrong. I don’t know (I doubt) if she will apply it to other contacts with the same surname, but it may be easier to do as you go than switching from voice command to text entry?
