The current lookup field for people will look for name, phone number, or email, but we have no way of scanning or entering a number. In many cases, people will be working from walk sheets or walk and call sheets, and we willl have a need to quickly look up a series of prospect to enter new information we have collected.  A form view would be useful, but just having he ability to add an additional box where you can enter the sequential number assigned by Nation Builder would be very useful,. This cannot co-exist with the current lookup box becaue many id numbers would look like the address  numbers from address fields.
