a.) I'm sorry but I don't understand. The suggested way is fast for only few links or mass selection. A chunk setting won't make it easier because either it affects all links in list, or it affects all fresh added links. I don't see any advantage over manual applying settings and/or packagize rules.
A chunk setting you still have to change settings for different host and what you want to achieve.
b.) worked fine here, can you provide screenshot of your rule or export it
