How can I create constraints for designer around a prefab structure?

Hi! As architect I want to create strict prefab with other prefab with model and collllider. For example:

I have Unit Prefab. How can I say, that every concrete unit must have a prefab with model and collider? It is possible?

Sure I can add properties into a script, but I can't validate right designer work in design time.

Sorry for my bad english (

UPDATE:

I can show example by code

For example: I have a class Unit

public abstract class Unit
{
    public Model Model { get; set; }
    public Collider Collider { get; set; }

    public Unit(Model model, Collider collider)
    {
        Model = model;
        Collider = collider;
    }

    // Other props and behaviours
}

So, when I inherit my class Unit in class Marine, I should post into the base constructor Model and Collider instances.

I want to reproduce this behavior in the design flow.

The issue names no files, tests, or entry points. First clarify how prefab composition and design-time validation are handled in Stride, then identify the relevant editor and prefab systems and define the expected validation behavior.
