Ah... so if you're not creating circuits first, then of course, you're going to be manually creating all the wiring.. and take forever to do it!
You can create circuits without circuiting to a panel.
I'd recommend you review the tutorial, starting on about page 248.... I think you will find the automatic method to save a significant amount of time.
