It is currently mandatory to specify the username of a package when constructing an ConanMultiPackager object, although it is already defined in the recipe to build. The same is true for the channel.

This could be easily changed without changing the current behavior when either the username/reference argument of ConanMultiPackager or the environment variables CONAN_CONANFILE/CONAN_REFERENCE are defined:

Could you please consider to integrate these changes? It would make our work much easier by reducing redundancy.

Thanks a lot in advance.
