Python packages support on power bi service

As of now there are only limited python packages available in power bi service , but it would be good if we can install/access additional python packages which are available officially on PYPI website for python visuals in power bi service . We are able to use additional packages in power bi desktop but can't use them on power bi service . It would be great if we can have adjustText (https://pypi.org/project/adjustText) package support on power bi service .
