If people find this please still upvote if you'd like this feature. The other request previously linked has been marked as complete (as you can now select git-bash). But there is currently still no support for PowerShell, so this feature request is still needed/active.

Sorry, I missed the one Mark linked. This one can be closed/merged to that one.
