Is there a way to associate custom type definitions to a code cell?

[yutao-huang]

I'm now building an extension based on this sample extension. The code cell in my notebook is using some custom modules. And I'd like the code IntelliSense support of them.

As a workaround I switched the language of the code cell into Typescript and explicitly injected a line at the top of each code cell like this:

///<reference path="the-absolute-path-to-the-d.ts-file"/>
...

Wondering if there is a better way so I don't have to manually inject this triple slash to clutter the code cell. Thanks!
