Description
According to the source code, only one objective can be added to a model. Instead of converting to single objective, how to optimize multi-objective problems?
if not overwrite:
assert self.objective.expression.empty(), (
"Objective already defined."
" Setoverwriteto True to force overwriting."
)

Research direction
Start by tracing the source code around the self.objective.expression.empty() assertion and the model objective API. Determine whether multi-objective optimization is supported by the project or its solver integrations, and identify the intended behavior and interface. Done should be a decided, documented approach or an explicitly scoped implementation plan.
