You are most welcome.
If you click above on EXTRAS, then PHOTO GALLERY, and the go to page 9, you can see the notebook bag combination I posted, along with our other Rimowa case photos.
Note that I have tried combinations with our Topas, a pilot case, and the attaché cases large and small. The notebook bag remains the best designed option, and will work very well with any of the two-pole carry handle Rimowa cases, large or small. The one in the photo is a Rimowa LH model purchased in Frankfurt. All are used and still going strong.
I could give you a list of a dozen or more Rimowa stores here, but seeing that you live in California, USA, I doubt that would be very useful.
Try the Rimowa Beverly Hills store on Rodeo Drive. They have been most helpful when visiting California: If they do not have the bags in stock, they can order them for you. They posted a few to me in just a few days via FEDEX when I was visiting Walnut Creek.
