Short answer: No. A true customer account feature is something we’re actively working on and plan to roll out in a future update.
Long answer: Technically you can do it now, however it will take a bit of custom development work. You could create a WordPress user and tie it to an Order ID via the order paid Webhook. Then you would need to figure out a way to save that data either in the post_meta table or some kind of custom table. The plugin can sync order and customer information.
