customize fields to display specific values

[anthonynunn30M]

some fields we can display can have multiple values, for example a Task resource has an identifier element which is a list of CodeableConcept

{
  "resourceType": "Task"
  "identifier": [
    { "system": "https://example.com/foo": "value": "foo" },
    { "system": "https://example.com/bar": "value": "bar" },
  ]
}

that identifier element can be displayed as a "field" in the UX but if there are multiple values all are shown
?fields=identifier

identifier
https://example.com/foo: foo https://example.com/bar: bar

if I know that I want to display the value for the identifier with the https://example.com/foo system there should be a way to specify only that system value should be displayed in the column
?fields=identifier:https://example.com/foo,identifier:https://example.com/bar

https://example.com/foo	https://example.com/bar
foo	bar

I have been using the medplum application as a developer and display ALL values of an element bogs down the UX making it less usable when most of the time I am looking for a particular system in a list.
