@AveryJohnson56 ...
Unfortunately, to my knowledge, there is no way I know of to do this. It's quite possible that each of your three schools have a different way to log in to their Canvas environments (even though the login screens may look similar). Each school may use a different authentication method to log in to their own Canvas environment. And, once logged in, each school most likely has their own method for course names and course numbers. Sorry that I don't have a better answer for you. The best thing you might try is to have three separate tabs open in your browser...one for each of the three Canvas environments for each school.
If you have additional questions about this, please post below...thanks!
