Is your feature request related to a problem? Please describe.
This isn't necessarily a problem, more so just a nice feature.

Describe the solution you'd like
I would like the ability to choose which versions of python the python and python3 commands get aliased too, as currently it is just aliased automatically. This could be achieved by a command like pymanager alias <python or python3> <tag>

Describe alternatives you've considered
None
