Suggestion: Annotation Field for Measures

In PBI Desktop, I would like to be able to right click on a measure in the Field list and have an annotation field where I can write some notes to myself about why I created the measure the way I did. Although in many cases it is clear why the measure was created just by looking at the syntax, there are many situations where an explanation would be very beneficial. Either because of the complexity of the measure or because of the unclear nature of the underlying data fields contained in the measure, I often find myself going back and trying to reconstruct my thought process on why I did something.
