Re: Turning the status of subset list ON without import
If I understand it correctly - you are asking if it possible to enter a formula for a subset checkbox in your product list:
Product Sales Module ExampleProduct List Example
Unfortunately it is not possible to enter a formula for a subset. Import is the only way to adjust it, apart form manually changing a value. However you could make users' life easier by adding the import Action to a Process that influences your Product Sales module data. That way whenever you update sales data - the subset list will be updated automatically, also while the product sales data does not change - subset will stay as it is.
