How can I increase the limits of the fine tuning jobs per day?

The gpt-4o-2024-08-06 model has a limit of 8 fine-tuning jobs per day, but I need to increase that.
Is anyone familiar with how to request a higher job limit?

Also, does “per day” refer to a calendar day (00:00 to 23:59) or a rolling 24-hour window?
