Workaround for Form Prefill

We're experiencing some trouble with our subscription center since the change to form pre-fill. If someone clicks the link in an email sent to them, everything is fine—as is expected with the change. But if they use the link on their personal account page on our website, the form can't show them what their current options are—as is expected with the change. This is causing some serious frustration with some of our members and has led some to just unsubscribe from everything, which is very much what we don't want to have happen.

Does anyone have a workaround so that our members can see which options they're subscribed to if they get to the link from a place other than a Marketo email?
