Wow - that’s great news.  Until that’s fully baked / released I have a pretty simple script I use to do this.  I generate a file per parent zone, and $INCLUDE it where needed.

You will likely need to change some of the variables near the top to suit your needs.  Also you may want to comment out the end parts that do the diff and emailing if you don’t care about that.  Emails should be extremely infrequent, but personally I’d like to know if/when they change,
