Add "notes" to the result page of the docs as well as the expectation page

Hi,

I am using great_expectations so that a not technical team can see outputs of the data testing via the docs and fix the input data files of my pipelines.

I need to give them more detailed notes than the outputs of the expectations so they can find the data issues. For example, instead of saying x number of rows fail a test, I would give them the names of the companies/etc that failed by taking the value from a different column.

This works in the expectations notes but means you need a new expectation for each data asset being tested. If there was some way to add custom "notes" to the validation pages of great_expectations that would be perfect!
