Dpendency in Change Execution

Hello,

Is it always necessary to clik and choose a flowdown status for every single item when Deoendency is set in a CA? With more complex changes, this becomes a little anoying. Is there a way around this?

Also, I didn't manage to fing an explanation for tehe choices a what they mean (Ignored, flowdown complete, etc.). I'm trying to better understand how dependency between CAs works and what benefits this bring to the user.
