How can I incorporate suet on the Feeder 2 Duo?

So I recently bought the Feeder 2 Duo to take the place of my low-tech feeder. The problem is that the new setup does not have a ready-made solution for suet, so there's a bunch of birds that are no longer visiting. I bought the Birdfy Pro Perch without realizing that it is totally incompatible with the 2nd generation feeders. It was not obvious to me and I didn't see any mention of it on the Amazon page. In any event, I'm looking for a perch that would work or some other attachment that might hold the 2.25 suet balls. Any help would be greatly appreciated.
