i want to add a subcategory to the 'intro' il for what the golf, splitting the versions but i don't know how

To add sub categories to ILs, click “Edit Game”, then click “Variables”. Next, you need to add a new variable. Click “New Variable” and fill out the name for said variable. Now you need to add values. Click “New Value”, and then fill out the name for said values. Then, you want to click the 3 dots next to the variable (not a value), click “Edit Value”. Then you want to check off “Use as a sub-category”. Next you go to the “level” setting in the variable, and change it from “Full game and IL” to just “IL”. You can also do the same thing with each level with the setting below “Level” if necessary to split sub categories for a single level. This same thing applies for adding sub categories for Full-game runs.
