Hello!
Thank you for your question. At the moment, the plugin doesn't support assigning odds to entire categories of items. In the current setup, each item must have its own individual odds, and there's no mechanism to automatically distribute a category's total odds among the items within it.
This is because the plugin is designed to calculate the odds for each item separately. If you want different probabilities for various items, each one needs to have its own specific value. While this gives you precise control over the odds for each item, it means there’s no functionality for setting a probability at the category level and having it split automatically across items in that category.
I hope this clarifies things! Feel free to reach out if you have any other questions.
Best regards.
