How to add scope to binding expressions in Delphi Live Bindings?

I know how to use live bindings on a form to bind one property to another property using an expression. For instance, binding a TLabel's Caption to a TEdit's text property.

I know how to create new expressions using IScope, TNestedScope, TDictionaryScope, etc. I can add my own classes and call them as scripted expressions.

What I don't know is how to take my new expression scope and make it available to the TBindExpressions in my TBindingList for use on a form when I'm doing things described in the first paragraph.

Anyone know how to do this? I've investigated, and I can't find a way to add an IScope reference to the binding expressions available to TBindingList and its sub-components.

David -- thanks for the response, but unless I am missing somthing, that isn't it. I need to be able to register/add IScope instances, or at least it appears like that. – Nick Hodges Apr 13 '14 at 22:39
Do you know that is how it is done? – David Heffernan Apr 14 '14 at 05:36
@DavidHeffernan -- Apparently not. ;-) – Nick Hodges Apr 14 '14 at 13:44
I was not clear. I mean do you know for sure that adding an `IScope` is how to solve your problem? – David Heffernan Apr 14 '14 at 13:45
No, I don't know that for sure. IScope is what is produced when you add scripting classes to the existing scope, however, so that is my assumption. – Nick Hodges Apr 14 '14 at 14:56
