Custom Raids

Heyo! Tameable here.

I was wondering if there is the ability to make a custom raid in 2025.1, as I checked and saw that in 2024.2, entities could be added to Minecraft raids, and as Minecraft 1.21 changed how bad omen works now, I was wondering If I was able to make a custom raid. (For example, I would make a zombie raid that could happen at the player's base.) 

I hope it's possible as It would allow me to make a lot of cool things possible in my mod, but if that's not possible then that's ok.

Anyways, See ya'll in the comments!
