if i import a csv spreadsheet with multiple invoices and multiple products, how can i add a column to create a message on the statment

Hi moische, thanks for joining us here on the Community. 🙂 It's not possible to add additional columns to the import data templates, and currently there is no field to map the 'message on statement', so this would need to be edited after importing. We'd be grateful if you could share any feedback you have on this by navigating to the Cog > Feedback within your account, this way your suggestions will be submitted directly to our developers for consideration. 

Thanks again!
