For many assignments - I use the same instructions through multiple classes and courses.  IE it may be instructions on how to do the assignment and have links to what to do if they need more resources.   In the instructions - I link to the 3rd party site with the latest information from that 3rd party (they update this page every year).  

However - the issue is - when that link changes - I now have to update every assignment's instructions.   Does anyone know of a way I can do this easier?  Is something where I can update the instructions in 1 place - versus having to update 50 assignments??   I was thinking of putting it in the rubric- but I saw if I do that I need to detach and reattach the rubric for each assignment.   

Thanks
