Request or WCIF No Phone Trait

Is there a way to disable the phone for individual sims. Since this is done for toddlers I thought it would be amazing if we could somehow add this function as a trait to specific sims. This would come in handy for some theme builds and challenges. I'm currently building an apocalyptic world with zombies. it's so annoying watching zombies stop and play on the phone. I've used the no autonomous mods as well, but its not 100%. it's got me thinking that it would be great to disable the phone for just those sims. 

Has anyone made anything like this? If not I guess it would be a good mod challenge. 

Thanks for reading. :D
