API question: How can I determine whether a subscriber is subscribed to a specific sequence? I can see that it's possible to download the entire sequence subscriber list, but that's too much data for my use case. I need a way (from the ConvertKit API) to get a list of the sequences a subscriber is included on. The subscriber details page shows the sequences the user is included in, but it appears that information is server rendered so I can't reverse engineer the API that's being used to get that information. My guess is this is currently unsupported which is a real shame. Is there any possibility to get this supported?
