Greetings, ChristopherKulow!
Thanks for reaching out to the Apple Support Communities! It sounds like you're wanting to change the frequency that you're billed for your purchases.
It looks like you've already reviewed the article titled: How apps, content, and subscriptions from Apple are billed. The "Multiple items might be grouped onto one bill" provides some great information about this. While there's not a way to change how your purchases are grouped, you can always send your suggestion to Apple here: Product Feedback
Have a great day!
