Thanks to you both, Richard and Frederik! I'm currently working on using both your suggestions to build out my Scrapbooks with certain devices. I guess my biggest complaint may not have been clear in the original post, or there at all. (I think I might have done the first time I wrote it, but my browser crashed when I tried to post the first time. I must've left this out when rewriting it!)
My biggest complaint was the lines between the plates and devices, especially the line-breaks/jumps at intersections. I know it can be done using 'Start' and 'End' arrow styles, because I've already made a riser diagram in LayOut, but it is certainly more of a pain than using a custom LSP to cut lines, then another LSP to pull the lines back a short distance. This is really the only bit I wish I could speed up (because after taking the time to eventually create/convert any common devices from CAD, I see the lifework connections as being the biggest time sink in LO).
