is there such a setting to allow you to right click on an address and have the drop down give you the option to add to a certain “group”? i know it ask to add to contacts – but then you have to go back in and drag/drop to group – where’s the time saver in that? if you can perform this ‘straight to group click’, can you shift and highlight more than one address to add several at once?

I'm pretty sure Automator's pre-made drag and drop actions are not enough to do something that specific. But you should be able to do it with AppleScript -- inside Automator or just using the AppleScript editor to build it. You would need programming knowledge, unless there is a sample script out there already that does it.
I found this page, which has a lot about AppleScript and Address Book:
