Add package to pyenv base interpreter

[Larz60+]

I would like to add the wxpython package to pyenv python 3.8.5 so that when I create a new virtual environment,
with pyenv global set to 3.8.5, wxpython is automatically included in the just created venv directory.
Is that easily done?
if so, how?

Maybe just create alias that creates virtual environment and afterwards it also installs the wxpython?
