Proposed functionality

#15104 allows customizing the appearance of dropdown lists in custom scripts for ObjectVars. I'd like to extend this functionality to support any object property or custom field in the context.

Use case

Here are two examples where I would use this in custom scripts.

We use a space_number custom field on each Location which references an external database run by the real estate team. I'd like to display that as the description like this:

    location = ObjectVar(
        model=Location,
        context={
            "description": "cf__space_number",
        },
     )

Note: that code doesn't work, but it's how I would like it work. If I use id instead, it looks like this:

Another example, in a PowerOutlet variable, I'd like to display the outlet type like this:

    outlet = ObjectVar(
        model=PowerOutlet,
        context = {
            "description": "type.label",
            "disabled": "_occupied",
        },
    )
