Dynamically update survey question response options using previously entered data

Hi--I have created a survey that the same person completes every time they have a meeting with a client; new clients are regularly added, each with a unique ID, and the survey completer is likely to meet with each client several times. Is there a way to automatically update a dropdown list of client IDs in the survey each time a new client is added?  Thanks for any ideas--my Qualtrics skills are pretty basic and I’m trying to make better use of the possibilities it offers.
