Your current methods are the fastest. If you have the BEGIN and END done correctly and have your figure prefix library set up correspondingly, then all of your line work should be done when you insert the field book file. A matter of seconds. (The begin and end replace "batch sequences".)
If you do this and also have your descriptor keys set up and running, there is no faster way to do this that I have seen yet.
This system gives you the ability to have your line work and blocks all done in a matter of minutes. I don't see how you can improve on that.
