Merge podcasts from different sources onto a single Apple Podcasts feed

Hi - I very much hope someone can help me with this podcast question. I started a podcast series using Soundcloud as a host but have since switched to using Anchor for more recent episodes. This means there are now two listings on Apple Podcasts for the same series and I want to bring them together as one single listing so listeners can find all the episodes in the same place. I don't know how to do this and would really appreciate some advice. Thanks in advance - Adam
