Hi @Carter41 

I'm not aware of a mass-cloning tool off the top of my head, but you might look at SIS imports as a mechanism to create new courses each term and automatically associate them with Blueprint courses with just a .csv file.  See https://community.canvaslms.com/t5/Admin-Guide/How-do-I-format-CSV-text-files-for-uploading-SIS-data... 

As an alternative to Blueprints, if you just need the courses copied and don't need to have the content locked down the way that Blueprints allow for, you might look at Templates (https://community.canvaslms.com/t5/Admin-Guide/How-do-I-select-a-course-template-in-an-account/ta-p/... ), depending on your sub-account structure.  Templates allow you to copy the contents of a template course into any course that is created under a particular sub-account, so you'd need a distinct sub-account for each course, and I'd still use SIS imports to bulk-create the courses for each term.
