In the 123 Survey we would like to develop a form where land managers will answer certain questions about a treatment site for invasive plant species. Then a contractor, who will be treating the infestation at that site, will enter data for another set of questions while doing the treatment. What is the best way to have different people enter fields about the same geo-location in Survey 123? The managers can potentially enter their data before or after the contractor treat the site. Also we will need to add follow-up post-treatment data for the same site e.g. a month, a year, or 2 years after the treatment. Thank you.
