Custom shell's arguments in 'Shell' system plugin

[FloatStream]

Is your feature request related to a problem? Please describe.

At present, Shell plugin can choose to use 'cmd', 'powershell', 'pwsh', or 'runcommand' (I am not sure what API this is). I would like to add an option that allows me to call cmd, powershell or pwsh with custom parameters and then run my command.

The main reason is that my pwsh configuration file sometimes takes about 1 second, and I use the flow plugin to quickly open a shell and run some commands, so I don't want to load the configuration file (pwsh/powershell can add the -nop option to not load the configuration).

Describe the solution you'd like

1. Add an option such as CustomShell to allow users to add a line of commands to call the shell.
2. Add a place to add custom parameters after the existing cmd, powershell, or pwsh options.

Here is a possible look

Describe alternatives you've considered

Although not adding this feature does not affect normal use, sometimes the experience may be worse.

Addition

If a developer has implemented this feature, I would greatly appreciate it. I'm very sorry that I don't know how to write C#, so I can't implement it by myself.
