For the stripe payment action, in customer information, there is a dropdown for the first name and a second dropdown for the last name of the customer.  On my form, I used the Name field, which automatically creates a firstname and lastname entry.  When I use the dropdown on the payment action, all I can get is the whole name field, first and last name together.  Short of not using the built-in name field and creating separate firstname and lastname text fields manually on my form, is there a way to retrieve the first name and lastname through the dropdown?
