We set up a dropdown with multiple events as a contact field. A customer can sign up for one or more events. We want to create an automation workflow whose "Update Contact" action adds the specific event information to this dropdown once a customer submitted a webform for the corresponding event. However, once they sign up for more than one event, and the workflow is triggered, the latest single entry in the dropdown will be overwritten.

Can you please introduce logic in workflows that allows for adding and removing from multiple dropdowns, just the way it works with tags?

Thank you!
