Looks like I spoke too soon without actually trying the Collections side again. Even with the modified channel numbers, seems like the this feature relies on the channel IDs rather than the channel numbers, and so this issue persists despite ignoring channel numbers from the HDHR's playlist. I tried the PUT request manually using the channel number and it does not reflect the channel correctly in the collection afterwards (claiming channel 2002 doesn't exist), so this seems like expected behavior and that collections are listing channel IDs on the backend rather than channel numbers.
@tmm1 Is there any way to handle this within Channels or does this use case require using workarounds like above to remap channel IDs from the original playlist?
