Improve UX: Rename Waterfall Columns for Clarity and Customization

Could be subjective, but a UX Feature Request - make columns in a waterfall take the default name of it's provider - instead of Find Work Email (3) they could be called Prospeo etc and then the validation columns would be Validate Prospeo instead of Validate Work Email (3) - way neater if you want to do any sort of a custom setup within each column of the waterfall and if you're not looking for this - Find Work Email (4) doesn't help much with anything.
