Moving information from columns into different boards

Hello! I am trying to create an overall board that will be picking up “leftover” information from a flow process. Example:

Board 1 - Board 2- Board 3- Board 4
Overall Board

While an item is moving down the line it will be picking up different columns and information however not every board will have the same column as the last expect the basics.

Example: Product Title will travel the full process but Order Qty will only be relevant in Board 2.

Is there a way to grab all the information from each board to then be dropped off into the Overall Board without making multiples of items or losing any information? The item still needs to travel the full process and still be fully updated.

If anyone has the answer to this that would be amazing, thank you!
