How can I add an update to a line item linked to another board without leaving the board

We work off one main campaigns board where all items are added. We then connect these line items to the individual team boards, and use mirror columns to share the key details. Previously, we were able to add an update to the linked board item without leaving the main board. However now, if we click the connect board and select “start conversation” it takes us out of our main board and into the individual boards. It was such a time saver to be able to add the update without leaving the board. Will this update be reversed?
