Mirror Board filtering

Hi, hopefully someone can help.

I’m trying to create a call logging board within our Monday.com setup. I would like to mirror the call logging board to another board that holds all our contacts, but first I would like to filter that list that appears by the customer name we choose in another column.

So an example would be:

Customer column: set this to ABC Contracts
Contact column: when we go to select the contact we only find the contacts that belong to ABC Contracts

I can easily setup a mirror board to the contacts board, but it shows all contacts and it can be difficult to narrow down where each contact belongs to.

Any help would be greatly appreciated.

Thanks
