Can I add customised columns to my client lists. So I can know certain actions have been done like a form sent etc?

Hi Anna-TheThoughTP, 

Thank you for reaching out and welcome to our community!

The function of adding additional columns onto the client lists is actually not available at the moment. However, you can see the form sent status by clicking into the customer and look at the transactions list. 

Please let us know if you require any additional assistance.
