When a customer pays an invoice that has a custom payment schedule (e.g. 50% / 50%); the first text message confirming reception of the payment automatically uses the default message as shown in the screenshot of the text message. There is no option to edit this message and change it to a custom message or even apply the custom snippet that is being used for a fully paid invoice.

At least it is necessary to apply the same custom message that is used for a fully paid invoice to the partial payment. Even better would be to have the option to edit and apply a custom snippet message for partial payments.

Thank you!
