How to use annotation to change the behavior of a get/set?

Question

I think the first question here is "It`s possible to change set/get behavior from a property using the annotation attached to it?"

I'm trying to automate a dictionary where when a property in the object is changed he will change the dictionary as well

This is an example from what I`m trying to do

public class Example : Dictionary<string, object> {

    public string Name { get => this["Name"].ToString(); set => this["Name"] = value; }

}

Making this automated would be something like:

public class Example : Dictionary<string, object> {
    
    [Field] //or [Field="name"]
    public string Name { get; set; }

}

and the annotation "Field" will make the set and get work properly with the dictionary. Is it possible?
