        "description": {
            "identifier": "minecraft:banner:4",
            "render_controllers": ["controller.render.item_default"],
            "materials": {
                "default": "entity_alphatest",
                "enchanted": "entity_alphatest_glint"
            },
            "textures": {
                "default": "textures/entity/banner/blue_banner",
                "enchanted": "textures/misc/enchanted_item_glint"
            },
            "geometry": {
                "default": "geometry.banner_blue"

            "animations": {
                "first_person_hold": "animation.banner_blue.first_person_hold",
                "third_person_hold": "animation.banner_blue.third_person_hold"
            },
            "scripts": {
                "animate": [
                    {
                        "first_person_hold": "c.is_first_person"
                    },
                    {
                        "third_person_hold": "!c.is_first_person"
                    }
                ]
            }

I don't believe that you can.

[vivid scaffold]

bruh

What is the data used for?

[vivid scaffold]

like different banner colors

[muted tangle]

You can add multiple texture to attachable using the render controller of the attacchable, like the horse skin. Then you can change this thexture using player propertirs and other query, but is a little advanced

[vivid scaffold]

code?

For multiple texture you can see the vanilla file of the horse for example: horse.entity.json and horse.render_controller.json
