gitui can not use "." option to ONLY see changes and logs in the current directory

[HHPLow]

Is your feature request related to a problem? Please describe.
Not related to any problem. When I want to see the current directory changes and log use gitui . or gitui -d <dir>, will always use whole git repository changes and log.

Describe the solution you'd like
Want to add an option like gitui . to see the changes and logs only is this directory, not the whole repository.

Describe alternatives you've considered
Now I can use git log ., git status . or tig .

Additional context
None
