Sorry I didn't get to this one earlier, unfortunately your correct it does only support the check boxes on each page. Which is really unhelpful.
At this time there is no UI fix available to allow for the 'delete all subscriptions' function. But I could delete all your subscriptions on the back end for you, but it would be awkward to pick and choose.. i.e. I could delete all or none.
I know this feature has been asked for before from our vendor but as yet its not been implemented. I will give it a nudge again for you.
