How do I import a rig made in Blender into Roblox with Motor6D already set up

I’ve already made a rig in Blender while following Roblox’s way of making characters. However, when importing the model into Roblox the motor6Ds are not in the place of the rig’s bone joint origin. How do I fix this so that I can import the model without having to tinker with it in studio?

Here is a photo of my rig in Blender in the object tab.
If you need more info, I can share it.

A little late but if you still haven’t figured it out if you export it as a .fbx it should work
