How to use reference qualifier in Select Box?

[RFJ1]

I have a variable that displays time zone for the user to select but I want only the choices whose language is English (en) to be displayed. 

How can I achieve that?  My variable page does not have the reference qualifier option. How to filter choices based on language?

Hi @Ankur Bawiskar In case I use a Lookup select box, please provide me the reference qualifier to filter the timezone value in en

Thanks
