The ability to control text form entry against a large dataset. For example, I have a form that went out to 1,500 employees. The primary column is their name. Now when I want to check who has vs. has not completed the form, I have to manually check for false negatives due to slight differences in how they typed their name into the form vs. how our directory lists their name (e.g. Johnny Doe vs. John Doe). I cannot make the primary column a dropdown to fix this, nor would I want to, as that would be a list of 1,500+ to scroll through. If I could set up a validation column that I could input our list of names from the directory, that would be a huge help.
