Scratch off cards

Has anyone successfully added the scratch off deals to an existing plan? Like the GHK deal customer service is helping me fix it so it’s not an urgent need to know right away since I know customer care is awesome and will definitely fix it for me but I’m curious in case I come across another deal this month.I tried to go through the intake and when it said you have this plan already manage it in your portal I clicked on it and nothing happened. 😩
