Is there a way to have a component binding’s expression reference it’s own properties without specifying the full path to the specific component through the root container?

For instance, if I have a custom property on a button called `code`, how would I access the property as essentially `{this.code}` instead of `{Root Container.Button1.code}` so I can copy-paste the button without having to change the binding?

Copy and paste of components in the designer updates such references for you. Otherwise, nada.

Strictly speaking, a function or method called from `runScript()` can reference properties via `self`, but not as bindings. Similarly, a one-liner in `objectScript()` can do the same via `binding.target`.
