Thanks for your answer. That's a pity.

So the only option I had is to write another custom importer, that 
mimics as much functionality of the default importer as is necessary so 
that I can insert it before the otjer custom importers.
In my current case this would be to import '.py' files from the current 
working directory.

Will try to find some docs.
