Yes you can.
If you're yet to implement/override members, then in a derived class or interface implementation, click Alt+Ins, choose "Overriding members" or "Implement missing members". In the wizard that displays afterwards, choose members to implement/override, and make sure to select "Copy XML documentation".
Alternatively, if you already have an overridden or implemented member in place, press Alt+Enter on the overridden/implemented member, and select "Copy comments from base".
