does anyone know if there is a way to bulk add a list of contacts to the do not call option? Really want to avoid doing each one individually. 
Is your do not call option a contact type? If so you just add them all to that contact type through an import under settings - import/export - customer importer. Just list the correct contact type in the correct column, and either their email address or customer number so the system can find them. You’ll probably select “do not overwrite” when you upload, because you probably won’t have all the other info filled in (although I think if columns are blank it won’t overwrite anyway though . . .)
