[Feature Request] Adding a bone under the skeleton root with a specific name

[semaphorelab]

I am trying to use your plugin to setup a Character Creator 4 character with IWALS (a variation of ALS that has motion matching support). Everything is working as expected except motion matching expects the character skeleton to have a bone named "attach" under the skeleton root. CC4 skeleton doesn't have it by default, I tried adding it as a virtual bone, as a socket, or even through the new skeletal editor in UE 5.4 and I tried through Blender but all of these do not work and either crash or wrongly deform the mesh.

Is it possible to have your script have an additional menu item under "Character Tools" that says "Add attach bone" that would add it to the skeleton under root at 0,0,0 and named attach (not skinned to anything, it's just a bone that is used by the motion matching system).
