We have a web application at our institution that is currently not using LTI integration. As as simple first step towards integrating into Canvas, I would like to add a Redirect Tool pointing to our web application. I can easily do this as an admin. And by clicking the Show in Course Navigation, the redirect appears in every course shell in whatever account I add the tool. However, I would like to make the tool disabled by default, thus allowing Teachers to add the too to their Course Shell's Navigation if they see fit. Any advice would be helpful, since I have not found an easy way to do this yet.
