How would this feature be useful?
Instead of:

$pip = @("internetarchive", "git+https://github.com/arecarn/dploy.git", "tubeup")
foreach ($p in $pip) {pipx install $p}

I will be able to do just pipx install internetarchive git+https://github.com/arecarn/dploy.git tubeup

Describe the solution you'd like
Allow installing multiple apps with pipx install

Describe alternatives you've considered
Using foreach or something like this.
