Duplicate Marketing Campaign Tasks

First of all, I'm trying to figure out how to build a marketing campaign for the first time. I created a marketing campaign that involved various tasks to send out postcards, etc. In the future, I want to duplicate this campaign for another set of leads. I tried to clone the marketing campaign but the tasks do not transfer. Can you please advise how to create marketing campaign templates so I don't have to recreate new marketing campaigns all the time?
