Support for file comparison tools

It would be nice if the Crucible could support configuring external File Comparison tools such as Beyond Compare. I believe that this can be done with SourceTree.

At my current employer we access Crucible from an on=premise instance view a web UI. It is Version:3.5.4 Build:20140917115234 2014-09-17

I find the user experience of file comparison tools like Beyond Compare much better than the web UI experience. I understand that it would be difficult to added or view comments when using a 3rd party tool. However, for many files under review I don't need to view or add comments to it. I would be happier if I could review the files in an external tool, but have to return to the Crucible UI to view or add comments.
