Yep, customer support helped me. Probably had something to do with being on the annual plan. All they had to do was cancel it so I probably could have done it myself but I probably wouldn't have gotten the full refund (though I just got charged for the annual subs few weeks ago so I probably would have gotten it regardless).In short, no, but depending on your current subscriptions they may not appear as options on your account page and you'll have to contact support to change to a bundle. For a thorough answer, you can look at this help article.
Customer support guy was great. After I thanked him and said he did a great job he responded with *gigachad face" but didn't have time to screenshot it.
So shoutout to John over at D+ support
