in forms, each transition button can have a conditions that has to be met to use it. If a user selects the option then they get an error message that may not be intuitive.

Can only transition buttons show up where the condition is met, or a button icon indicator that means the condition has not been entered. We would like to not have to relying on an error message for communication to the user entering the form data?

Or can there be a custom messages entry for each condition set that will show up if the requirement is not met?
