Execute C# scripts with a button or support #load in Macros

Is it possible to create a button in TE3 that executes a C# script on my local machine, stored in a path I specify? It would be awesome to have that ability. This way, I can have my scripts in source control, edit them with an external editor and execute the latest version from within TE3 every time I have to test them. Alternatively, you could support the #load operator when saving as a Macro. - -
