Splits defaults allow you to set values for your listings to preset splits
In this first part, you can set the default splits to compare against for each different listing pack quantity. You are able to select multiple split levels for each pack quantity
Toggling this option "On" will automatically adjust splits if part of your listing pack sells and the quantity remaining goes down, making the splits you set invalid. On the next pricing cycle, the splits will adjust to your default selection for what the new quantity is.
