Include or global block

Where I work, we reuse many block from a library of blocks that we created. With the template system, if one of these blocks gets updated, then many of the same updates need to be made to each copy or instance of the original block. This makes for mindless work that a computer or server could do much better.

What is needed is for a global block that works as a server "include" would. That is a block that goes to get the source original and automatically include it in the course. That way if the original source block is updated, all the instances of that block would also be updated across all courses that have it.
