Hey Brandon,
Thanks for reaching out!
You can import events into one parent category, but there are unfortunately two limitations at present:
• All of the imported events will go into this one category.
• No, there is no subcategory support.
I’m really sorry about both facts! 🙁 We’re hoping to improve this in the coming months and beyond, but these are the the current limitations and unfortunately are going to take a significant amount of time for us to improve these features.
I hope this information, while a bit of a bummer, is clear and helpful—let me know if that’s the case, or if there’s anything else I can try to help with!
Thank you,
George
