Weight mapping can be introduced into any figure within PP2014. You just need to WM paint the rough parts and double check the bending joints.

It can be even easier than that:
Click "merge Zones To Weight map" in the Joint Editor. It will create a weight map according to the sphere zone, and you can work from this instead of painting a weight map from scratch.
Now you can delete the Sphere Zone, or set the Weight map to "Replace" mode - don't use "Multiply" or "Add" because it'll give you funny results.
