How to connect multiple boards to a main board with one single column

Hello everyone I’m currently making boards for every single product I have and I want to connect those boards with a main board that holds the basic information of them (name, surname, status etc…) currently I’m using the Monday integration that creates an item in a board and connects them with a column (image below)

The problem is that everytime i want to use this automation I need to create a new column to link the product board with the main board (example below)

Want I want to achieve it’s one single column that can connect multiple boards , right now I only have 4 but in a future i want to have over 100 products and I don’t want to have 100 columns just for connecting boards.

Thx in advance
