Provide formula access to the idea associated promoted item

I'm creating various reports and custom worksheets (Enterprise+), where I can get information from the Feature to the Idea which generated it (to be more precise the idea which was promoted to a feature).

It would also be very helpful if somehow I can get the same information from the idea, which means retrieving information about the feature the idea was promoted to.

I know it could be tricky to define a proper method as the idea can be promoted to several different items, but this could come very handy when creating custom formulas and worksheets.
