Hey @TJ_S ,
I’m afraid that multi-board mirroring (i.e. to reflect data from multiple boards within the same column) is currently still an Alpha feature and is released to a selected list of accounts. I’m really sorry for the inconvenience, but we might not be able to provide the feature to your account just yet.
Is there anything else we can help you with? Also, I would recommend reaching out with specific platform-related questions to our inbox → firstname.lastname@example.org, as the best place to get this kind of help This section of the community forum is rather meant to clarify apps and API usage.
