Scheduling email campaigns by audience

We are looking for a way to schedule delivery of email campaigns by audiences - we are a b2b2c company and require the ability to schedule campaigns by business across 100s of businesses on a common campaign.    is there a way to create a canvas that allows us to schedule delivery across 100s of customers across different days w/in a month?  We would prefer not to create a canvas per business but to use the common email template and audiences and then break out by some type of segment or filter on when to deliver across which business.
