Not really. import_mod is simply the equivalent of saying 'import combo' in
python code. If you want to import everything in combo as top-level names,
you want 'from combo import *', which in the config file is spelled

alias is for _system_ aliases. Simply make a normal python function that does
what you want and load it as part of your startup process, and you're done.
