At my job, we are using Survey123 to collect observational data for different species of wildlife. When we find and catch these species, we give them codes so that we can monitor and record recaptures. We have a bank of codes which we loaded into a survey123 drop-down list. Right now we are manually combing the list on a weekly basis and then moving the used codes to a second drop-down list that contains used codes. Is there a way to automate the removal of a code once it is used? And is there a way to automate the process of adding the used code to the second list?
