Unhide Hidden Column Automation

So I’m trying to connect multiple boards. I have a “Project” board and need to connect tasks to multiple teams and to their separate team boards. I connected multiple boards in one connect board column, but the connection does not automatically populate and needs to be selected. Is there a way to make this work so they don’t have to manually select the task they just assigned to another board? Right now, because of that limitation, I have multiple connect board columns for each board. This is a bit unruly in my opinion, especially if there are 10 other department boards to assign to for one project. Is there a way to keep columns hidden until data is entered? If there is another way to make this work I could use a solution for our client. Thanks!
