The simplest way to achieve this is to utilize the Wish List functionality. Then, to change the words from Wish List to Draft List, just use the sys_ui_message table and search for all messages that contain wish list. Update those and then add all the missing ones and you'll get fully supported OOB functionality with the wording that makes more sense.
I've put together an update set with all the necessary messages as needed. Just import into your instance and commit the update set and you'll be all set. You can still update all the messages as you see fit.
