Did you meant you want to import data from different data source into the jotform submission data?
The required data source should be in CSV file format.
You can pre-populate the form instead so that the 'client number' can be included already during form submission. You can use the JotForm Field Prepopulator App
Hope this help. Please inform us if you need further assistance.
