Ability to have conditional values based off of environment (QA or production), like a .env file in code

Similar to how you might have a .env in code to differentiate between the QA and production environments, it would be useful for the Builder editor to have the ability to do conditional values based off of the environment.

For example, you might have a form created on the Builder editor that submits to a URL. It would be very useful to have the form method be dynamic based off of the environment worked on.
