Does MARLlib support a mixed scenario where each agent has a different policy?

[terranovafr]

I was wondering whether the library supports currently the mixed scenario (e.g. two competitive teams with cooperative agents inside) but allowing the possibility of having no policy sharing across teams and inside teams?

If in the policy_mapping_dict I set :
"all_agents_one_policy": False, "one_agent_one_policy": False,
while keeping:
mappo.fit(env, .... share_policy='individual', ....)
I receive the following error:
agent number too large, we disable no sharing function
