What is the best way of altering the "bp.registration.form.php" file

I am using the membership plugin and Buddypress to add some custom registration fields. Unfortunately, I am not happy with the location of the field's description. I found the line of code I need to change in the bp.registration.form.php file.

My concern is the changes will be overwritten when the plugin is updated. Therefore, is there a way I can add this file to my Child Theme so updating Membership will not hose my modifications?
