Indirect Bidirectional Property Binding

I have a need to create an indirect bidirectional property binding and I'm wondering if that's possible.

I have 3 properties on the root container of a template that are indirect bidirectional tag bindings. I want to be able to conditionally set one of these to then bidirectionally bind to a slider input.

I know how I could do it using a dynamic indirect bidirectional tag binding, but I'd rather keep my tag bindings to those internal properties rather than going directly to the tag.

Nope, sorry.

Alright, guess I'll dynamically create an internal string and use that in an indirect binding then...
