Change default terminal for custom commands

Hey, I'm playing with custom commands and can't find docu/config to change the default terminal.

**Describe the solution you'd like**
I would like to change the default terminal path and parameters.

**Describe alternatives you've considered**
Right now we can kind of start powershell from CMD -_-
`pwsh.exe -NoProfile -WindowStyle Hidden -command "& { gps > ps.txt}"` - this does not work

I have found some documentation about `subprocess` in custom commands. Now, I'm running lazy-git in Powershell 7 and WindowsTerminal. It looks like whatever I choose to use subprocess or not I will end in CMD. Although I would expect it to be Powershell 7.

Thanks
