String interpolation for fields

Hi! Is there a way to do string interpolation within Prismic field? I want to be able to pass whatever value like this:

Hello {{first_name}}! ....

then have that value displayed like this (if we pass John):

Hello John! ....

Hello @hamza.salah

Welcome to the Prismic community, and thanks for reaching out to us.

It's not possible inside the Prismic editor. We give values directly to any Prismic field and retrieve them on the front end based upon some kits and the helper functions.
