Adding additional CSV data to an existing population
To add new data to a population from a CSV file, you will first need to upload the new CSV data.
This is similar to how you would normally upload data from a CSV, but there is one important difference: you must select an existing table name. The table is used to create your population, so when added to the table, it will be automatically added to any populations that are based on that table.
Type the name of an existing table name. You will notice that it says "Add data to..." followed by the table name.
2. Select the table name when it appears.
3. Follow the rest of the instructions for uploading CSVs and the data will be added to the table that you select.
Viewing the additional data
Now that you added new data from your CSV, the population will include the new data.
