issue descripsion:
when i add "change A to Z plugins" and i want to apply muti-layer change e.g. layer No.1 to No.19, then i choice apply to "target layer+subsequent layer "but it not show subsequent layer which i can set.
not sure if it is bugs or other issue?

Subsequent layers keeps the change for _all_ subsequent layers rather then reverting the change for the next (as opposed to 'single layer'). If you want to change multiple _specific_ layers, you'll have to add multiple ChangeAtZ scripts in the 'single layer' mode.
So for instance you'd add a ChangeAtZ script that changes at layer 1 and subsequent layers, the print speed to 150%.
Then you'd add another ChangeAtZ script that changes from layer 19 and subsequent layers, the print speed to 66.7%, resulting in the rest of the print being printed at 100% speed again.
thanks team, it seems work now
