Text Message Option On Pre-register Page

Is there any update on adding an optional field to enter a mobile number to receive text messages when Pre-registering for a gallery. 

Or is there a way to have the customer create an account?

Any existing customers with cell phone numbers and texting enabled receive text messages when I send out the notification that the gallery is live. Just worried emails going to spam

There is not an option to collect phone for preregistration at this time. On the to-do list but don't know when.

You can  select "'Require customers to log in to view galleries' option in that section settings to require them to create an account.
