Or you can add it to a custom plugin, which will survive your theme's updates. See Jason's article, here: [https://www.paidmembershipspro.com/create-a-plugin-for-pmpro-customizations/]

Is there any way to add the new data to the admin confirmation mail?

I cannot edit this file anymore to improve it, but it needs sanitization and escaping to make it secure.

A better way to do stuff like this is with the PMPro Register Helper Add On. Docs here: https://www.paidmembershipspro.com/add-ons/pmpro-register-helper-add-checkout-and-profile-fields/
