Highlight field where error occurs

Ran into a situation today where I have a project that has 27 calculated columns in one step. The error message I received was: “Unexpected text after the end of expression. Error position 60.”

It would be very helpful if there could be an error icon or some type of color in/on/around the calculated column where the error is occurring. For my issue, the easiest solution was to generate the project documentation so I could see all expression editors in full in one screen. Original error pasted below and suggested feature request pasted below that screenshot.
