Is it possible to configure the following query?

Hi, I have the following config

{
  product: {
    label: "Product",
    type: "!struct",
    mode: "struct",
    subfields: {
      exceptions: {
        label: "Exceptions",
        type: "!group",
        mode: "array",
        subfields: {
          id: {
            label: "Exception Customer ID",
            type: "text",
          },
        },
      },
    },
  },
  customer: {
    label: "Customer",
    type: "!struct",
    subfields: {
      id: {
        label: "Customer ID",
        type: "text",
      },
      name: {
        label: "Customer Name",
        type: "text",
      },
    },
  },
}

How can I check if all elements inside product.exceptions doesn't have id = customer.cuid? When I select Field as value source, it doesn't show any options.
