There's no 8-switch Stomp mode in Stadium; both Stomp A and Stomp B are 10-switch. We ditched it because eventually, there'll be a better solution and we didn't want methods conflicting with one another. In the meantime, you can assign FS1 to Bank Up and FS7 to Bank Down from the Command Center, but this is per-preset. Easy to copy/paste them into other presets tho'.
