Yes. The Custom Rig workflow lets you map the main bones of an existing humanoid armature and generate animation controls over it. Bone detection is provided as a starting point, but you should verify the assignments before creating the rig.

Mecha Bind assigns separate rigid mesh objects to their closest bones. It is designed for robots, mecha, armour and other hard-surface characters made from individual parts. It is not intended to replace smooth skin weighting for organic characters.

Yes. The workflow is separated into three stages: Create Guides → Build Skeleton → Create Rig This gives you a chance to inspect and correct the skeleton before generating the final control rig.
