I am trying to setup a zap between ticket tailor and pipedrive that will update a multiple option field on a persons record in our CRM when they have purchased a ticket to our annual conference.
The multiple option field has values defined for each year, so the field is used to record which years people have attended our conference in the past, example below.
When trying to add information to this field from zapier, we are only able to add one option, and when running the zap it overwrites any values already in the field. Given this is a multiple option field, is there a way for the information not to be overwritten and a value be added to the existing?
