Great set, definitely a must buy for me! I do have a hang up, though; considering that I use a UK ISO format, and I'm going to go all in on purchasing the Base with the Addition, Aesthetic and Modern kits, it's a little annoying that I would have to purchase the Norde set as well just for the addition of the ISO number 4 key cap (split dollar & symbol format). Is there any way that this single keycap could be included in the Addition set? I don't object to paying more for this one key, and as a completionist it would bug me if I didn't get it... Please advise!
