How to explode in a direction other than the x-y-z axes?

Is there a way to do this?

The way I explode things in assemblies now is, I go ahead and create a configuration, insert an exploded view, and place parts at positions relative to their axes. Maybe there is a more sophisticated explosion function that I don't know of?

I'd like to be able to explode the higlighted cap in the attached picture along the direction which the adapter is facing (2 o'clockish)

Anyone?
