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.
