Hello there @PoV2000,
Thanks for taking the time to post in the community! We are thrilled to have you with us 🙂
After checking into this a bit further, this inability to split orders in bulk is intentional. There is not a process or button you have missed or have not enabled. This is simply intended to be a single order functionality.
Please feel free to post on our "Feedback" board here in the community to bring the desire of this feature addition to our product team!
Thanks in advance for your feedback, we truly appreciate it as we move forward to try and make the best possible platform we can for you!
