Yes, there are a couple of ways to do this.
- The best way is to export (from the design screen) both forms to excel, identify the fields you would like to copy from one form, then copy and paste the entire rows into the excel spreadsheet of the form into you want the fields copied. Then save this excel document and import it to your form design.
- Clone the first form and then edit the cloned form to suit your needs.
- If you're only looking to copy fields within the same form, there is a small double box icon that you can click and the field will be copied. Please be sure to check the data name of your copied field and then make appropriate edits and save.
