Can I change worker from one Provider to another?

When a worker is setup under one provider such as IM and transfers to CWS, is there a way for me to change the provider without deactivating the worker in IM and setting that person up again in CWS? I can change other info; supervisor name, workers name etc. but I couldn't find a place to change provider.

RESPONSE
No. The worker had an IM life and now has a separate CWS life.
