Create Customer Accounts After Contact Form/ Update Timeline

I would be great if after a person fills in a contact form they were atomically added as a customer on Shopify and the time line was updated saying what time and date they left a contact form so you could link it with the email. Within this if the customer is already existing the timeline would be updated within their existing customer account.

This would also link in nicely with my other request of email newsletter subscribers be added from contact forms.
