At the moment form the UI script/automation builder, whenever i call a script directly from the UI, the fields defined in the script are shown so they can easily be filled. When calling a script via the script.turn_on, the only way to pass data to the fields is via yaml. It would be great if the UI builder would allow for filling the fields for a script if using either the direct call or script.turn_on. I find the builder is easy to follow and think it improves HA a ton, especially for beginner users.
This is unlikely to happen because script.turn_on accepts multiple script entities which will not have the same fields.
I see what you are saying, thanks for the explanation. Just thought it would be a nice UI touch. Maybe, since 98% of the time the script.turn_on it is against a single script, allow for UI fill on a single script, but not on multiple? Just a thought.
